+ *   Soft Volume Control
+ *
+ * The external code supplies an 8-bit volume (attenuation) value in the
+ * 0 .. 255 range. This represents 0 to -96dB attenuation where an input
+ * value of 0 corresponds to -96dB and 255 corresponds to 0dB (unchanged).
+ *
+ * Each step thus correspons to 96 / 256 or 0.375dB. Every 6dB (16 steps)
+ * represents doubling the sample value.
+ *
+ * For internal use, the volume control needs to be converted to a 16-bit
+ * (sort of) exponential value between 1 and 65536. This is used with fixed
+ * point arithmetic such that 65536 means 1.0 and 1 means 1/65536.
+ *
+ * For actual volume calculation, 33.31 fixed point is used. Maximum (or
+ * unattenuated) volume is represented as 0x40000000; conveniently, this
+ * value fits into a uint32_t.
+ *
+ * To enable fast processing, the maximum volume must be a power of two
+ * and must not have a sign when converted to int32_t. While 0x80000000
+ * violates these constraints, 0x40000000 does not.

-  * TODO: The lwIP source code makes some invalid assumptions on processor
-    word-length, storage sizes and alignment. See the mailing lists for
-    problems with exoteric (/DSP) architectures showing these problems.
-    We still have to fix some of these issues neatly.
-
-  * TODO: the ARP layer is not protected against concurrent access. If
-    you run from a multitasking OS, serialize access to ARP (called from
-    your network device driver and from a timeout thread.)
-
-  * TODO: the PPP code is broken in a few ways. There are namespace
-    collisions on BSD systems and many assumptions on word-length
-    (sizeof(int)). In ppp.c an assumption is made on the availability of
-    a thread subsystem. Either PPP needs to be moved to contrib/ports/???
-    or rearranged to be more generic.
-    
-  * TODO: review the the sequential netconn and socket API (lwip/src/api)
-    for bugs and performance issues. Frequent system calls (e.g. sys_mbox_fetch)
-    slooow things down considerably.

-(STABLE-1_1_1)
-
-  2006-03-03  Christiaan Simons
-  * ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
-    access and added pbuf_alloc() return value checks.
-
-  2006-01-01  Leon Woestenberg <leon.woestenberg at gmx.net>
-  * tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
-    now handled by the checksum routine properly.
-
-  2006-02-27  Leon Woestenberg <leon.woestenberg at gmx.net>
-   * pbuf.c: Fix alignment; pbuf_init() would not work unless
-     pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)
-
-  2005-12-20  Leon Woestenberg <leon.woestenberg at gmx.net>

-
-  2005-12-14  Leon Woestenberg <leon.woestenberg at gmx.net>
-  * tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
-    Added Curt McDowell's optimized checksumming routine for future
-    inclusion. Need to create test case for unaliged, aligned, odd,
-    even length combination of cases on various endianess machines.
-
-  2005-12-09  Christiaan Simons
-  * inet.c: Rewrote standard checksum routine in proper portable C.
-
-  2005-11-25  Christiaan Simons
-  * udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
-  * *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
-    u32_t, s32_t typedefs. This solves most debug word-length assumes.  
-
-  2005-07-17 Leon Woestenberg <leon.woestenberg at gmx.net>
-  * inet.c: Fixed unaligned 16-bit access in the standard checksum
-    routine by Peter Jolasson.
-  * slipif.c: Fixed implementation assumption of single-pbuf datagrams.
-
-  2005-02-04 Leon Woestenberg <leon.woestenberg at gmx.net>
-  * tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch.
-  * tcp_{out|in}.c: Applied patch fixing unaligned access.
-
-  2005-01-04 Leon Woestenberg <leon.woestenberg at gmx.net>
-  * pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.
-
-  2005-01-03 Leon Woestenberg <leon.woestenberg at gmx.net>
-  * udp.c: UDP pcb->recv() was called even when it was NULL.
-
-(STABLE-1_1_0)
-
-  2004-12-28 Leon Woestenberg <leon.woestenberg at gmx.net>
-  * etharp.*: Disabled multiple packets on the ARP queue.
-    This clashes with TCP queueing.
-
-  2004-11-28 Leon Woestenberg <leon.woestenberg at gmx.net>
-  * etharp.*: Fixed race condition from ARP request to ARP timeout.
-    Halved the ARP period, doubled the period counts.
-    ETHARP_MAX_PENDING now should be at least 2. This prevents
-    the counter from reaching 0 right away (which would allow
-    too little time for ARP responses to be received).
-    
-  2004-11-25 Leon Woestenberg <leon.woestenberg at gmx.net>
-  * dhcp.c: Decline messages were not multicast but unicast.
-  * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
-    Do not try hard to insert arbitrary packet's source address,
-    etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD. 
-    etharp_query() now always DOES call ETHARP_TRY_HARD so that users
-    querying an address will see it appear in the cache (DHCP could
-    suffer from this when a server invalidly gave an in-use address.)
-  * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
-    comparing network addresses (identifiers), not the network masks
-    themselves.
-  * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
-    IP address actually belongs to the network of the given interface.
-
-  2004-11-24 Kieran Mansley <kjm25 at cam.ac.uk>
-  * tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.
-
-(STABLE-1_1_0-RC1)
-
-  2004-10-16 Kieran Mansley <kjm25 at cam.ac.uk>
-  * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
-	even if one is already pending, if the rcv_wnd is above a threshold
-	(currently TCP_WND/2). This avoids waiting for a timer to expire to send a
-	delayed ACK in order to open the window if the stack is only receiving data.
-
-  2004-09-12 Kieran Mansley <kjm25 at cam.ac.uk>
-  * tcp*.*: Retransmit time-out handling improvement by Sam Jansen.
-
-  2004-08-20 Tony Mountifield <tony at softins.co.uk>
-  * etharp.c: Make sure the first pbuf queued on an ARP entry
-    is properly ref counted.
-
-  2004-07-27 Tony Mountifield <tony at softins.co.uk>
-  * debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
-    warnings about comparison.
-  * pbuf.c: Stopped compiler complaining of empty if statement
-    when LWIP_DEBUGF() empty.  Closed an unclosed comment.
-  * tcp.c: Stopped compiler complaining of empty if statement
-    when LWIP_DEBUGF() empty.
-  * ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
-  * inet.c: Added a couple of casts to quiet the compiler.
-    No need to test isascii(c) before isdigit(c) or isxdigit(c).
-
-  2004-07-22 Tony Mountifield <tony at softins.co.uk>
-  * inet.c: Made data types consistent in inet_ntoa().
-    Added casts for return values of checksum routines, to pacify compiler.
-  * ip_frag.c, tcp_out.c, sockets.c, pbuf.c
-    Small corrections to some debugging statements, to pacify compiler.
-
-  2004-07-21 Tony Mountifield <tony at softins.co.uk>
-  * etharp.c: Removed spurious semicolon and added missing end-of-comment.
-  * ethernetif.c Updated low_level_output() to match prototype for
-    netif->linkoutput and changed low_level_input() similarly for consistency.
-  * api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
-    of raw_recv() in raw.h and so avoid compiler error.
-  * sockets.c: Added trivial (int) cast to keep compiler happier.
-  * ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.
-  
-(STABLE-1_0_0)
-
-  ++ Changes:
-
-  2004-07-05 Leon Woestenberg <leon.woestenberg at gmx.net>
-  * sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure
-    your cc.h file defines this either 1 or 0. If non-defined,
-    defaults to 1.
-  * .c: Added <string.h> and <errno.h> includes where used.
-  * etharp.c: Made some array indices unsigned.
-
-  2004-06-27 Leon Woestenberg <leon.woestenberg at gmx.net>
-  * netif.*: Added netif_set_up()/down().
-  * dhcp.c: Changes to restart program flow.
-
-  2004-05-07 Leon Woestenberg <leon.woestenberg at gmx.net>
-  * etharp.c: In find_entry(), instead of a list traversal per candidate, do a
-    single-pass lookup for different candidates. Should exploit locality.
-
-  2004-04-29 Leon Woestenberg <leon.woestenberg at gmx.net>
-  * tcp*.c: Cleaned up source comment documentation for Doxygen processing.
-  * opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC.
-  * etharp.c: update_arp_entry() only adds new ARP entries when adviced to by
-    the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option.
-
-  ++ Bug fixes:
-
-  2004-04-27 Leon Woestenberg <leon.woestenberg at gmx.net>
-  * etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution
-    suggested by Timmy Brolin. Fix for 32-bit processors that cannot access
-    non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix
-    is to prefix the 14-bit Ethernet headers with two padding bytes.
-
-  2004-04-23 Leon Woestenberg <leon.woestenberg at gmx.net>
-  * ip_addr.c: Fix in the ip_addr_isbroadcast() check.
-  * etharp.c: Fixed the case where the packet that initiates the ARP request
-    is not queued, and gets lost. Fixed the case where the packets destination
-    address is already known; we now always queue the packet and perform an ARP
-    request.
-  
-(STABLE-0_7_0)
-
-  ++ Bug fixes:
-
-  * Fixed TCP bug for SYN_SENT to ESTABLISHED state transition.
-  * Fixed TCP bug in dequeueing of FIN from out of order segment queue.
-  * Fixed two possible NULL references in rare cases.
-
-(STABLE-0_6_6)
-
-  ++ Bug fixes:
-
-  * Fixed DHCP which did not include the IP address in DECLINE messages.
-
-  ++ Changes:
-
-  * etharp.c has been hauled over a bit.
-
-(STABLE-0_6_5)
-
-  ++ Bug fixes:
-
-  * Fixed TCP bug induced by bad window resizing with unidirectional TCP traffic.
-  * Packets sent from ARP queue had invalid source hardware address.
-
-  ++ Changes:
-
-  * Pass-by ARP requests do now update the cache.
-
-  ++ New features:
-
-  * No longer dependent on ctype.h.
-  * New socket options.
-  * Raw IP pcb support.
-
-(STABLE-0_6_4)
-
-  ++ Bug fixes:
-
-  * Some debug formatters and casts fixed.
-  * Numereous fixes in PPP.
-
-  ++ Changes:
-
-  * DEBUGF now is LWIP_DEBUGF
-  * pbuf_dechain() has been re-enabled.
-  * Mentioned the changed use of CVS branches in README.
-
-(STABLE-0_6_3)
-
-  ++ Bug fixes:
-
-  * Fixed pool pbuf memory leak in pbuf_alloc().
-    Occured if not enough PBUF_POOL pbufs for a packet pbuf chain.
-    Reported by Savin Zlobec.
-
-  * PBUF_POOL chains had their tot_len field not set for non-first
-    pbufs. Fixed in pbuf_alloc().
-
-  ++ New features:
-
-  * Added PPP stack contributed by Marc Boucher
-
-  ++ Changes:
-
-  * Now drops short packets for ICMP/UDP/TCP protocols. More robust.
-
-  * ARP queueuing now queues the latest packet instead of the first.
-    This is the RFC recommended behaviour, but can be overridden in
-    lwipopts.h.
-
-(0.6.2)
-
-  ++ Bugfixes:
-
-  * TCP has been fixed to deal with the new use of the pbuf->ref
-    counter.
-
-  * DHCP dhcp_inform() crash bug fixed.
-
-  ++ Changes:
-
-  * Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
-    pbuf_refresh(). This has sped up pbuf pool operations considerably.
-    Implemented by David Haas.
-
-(0.6.1)
-
-  ++ New features:
-
-  * The packet buffer implementation has been enhanced to support
-    zero-copy and copy-on-demand for packet buffers which have their
-    payloads in application-managed memory.
-    Implemented by David Haas.
-
-    Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
-    if an outgoing packet can be directly sent on the link, or perform
-    a copy-on-demand when necessary.
-
-    The application can safely assume the packet is sent, and the RAM
-    is available to the application directly after calling udp_send()
-    or similar function.
-
-  ++ Bugfixes:
-
-  * ARP_QUEUEING should now correctly work for all cases, including
-    PBUF_REF.
-    Implemented by Leon Woestenberg.
-
-  ++ Changes:
-
-  * IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
-    to a '0.0.0.0' IP address.
-
-  * The packet buffer implementation is changed. The pbuf->ref counter
-    meaning has changed, and several pbuf functions have been
-    adapted accordingly.
-
-  * netif drivers have to be changed to set the hardware address length field
-    that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
-    See the contrib/ports/c16x cs8900 driver as a driver example.
-
-  * netif's have a dhcp field that must be initialized to NULL by the driver.
-    See the contrib/ports/c16x cs8900 driver as a driver example.
-
-(0.5.x) This file has been unmaintained up to 0.6.1. All changes are
-  logged in CVS but have not been explained here.
-
-(0.5.3) Changes since version 0.5.2
-
-  ++ Bugfixes:
-
-  * memp_malloc(MEMP_API_MSG) could fail with multiple application
-    threads because it wasn't protected by semaphores.
-
-  ++ Other changes:
-
-  * struct ip_addr now packed.
-
-  * The name of the time variable in arp.c has been changed to ctime
-    to avoid conflicts with the time() function.
-
-(0.5.2) Changes since version 0.5.1
-
-  ++ New features:
-
-  * A new TCP function, tcp_tmr(), now handles both TCP timers.
-
-  ++ Bugfixes:
-
-  * A bug in tcp_parseopt() could cause the stack to hang because of a
-    malformed TCP option.
-
-  * The address of new connections in the accept() function in the BSD
-    socket library was not handled correctly.
-
-  * pbuf_dechain() did not update the ->tot_len field of the tail.
-
-  * Aborted TCP connections were not handled correctly in all
-    situations.
-
-  ++ Other changes:
-
-  * All protocol header structs are now packed.
-
-  * The ->len field in the tcp_seg structure now counts the actual
-    amount of data, and does not add one for SYN and FIN segments.
-
-(0.5.1) Changes since version 0.5.0
-
-  ++ New features:
-
-  * Possible to run as a user process under Linux.
-
-  * Preliminary support for cross platform packed structs.
-
-  * ARP timer now implemented.
-
-  ++ Bugfixes:
-
-  * TCP output queue length was badly initialized when opening
-    connections.
-
-  * TCP delayed ACKs were not sent correctly.
-
-  * Explicit initialization of BSS segment variables.
-
-  * read() in BSD socket library could drop data.
-
-  * Problems with memory alignment.
-
-  * Situations when all TCP buffers were used could lead to
-    starvation.
-
-  * TCP MSS option wasn't parsed correctly.
-
-  * Problems with UDP checksum calculation.
-
-  * IP multicast address tests had endianess problems.
-
-  * ARP requests had wrong destination hardware address.
-
-  ++ Other changes:
-
-  * struct eth_addr changed from u16_t[3] array to u8_t[6].
-
-  * A ->linkoutput() member was added to struct netif.
-
-  * TCP and UDP ->dest_* struct members where changed to ->remote_*.
-
-  * ntoh* macros are now null definitions for big endian CPUs.
-
-(0.5.0) Changes since version 0.4.2
-
-  ++ New features:
-
-  * Redesigned operating system emulation layer to make porting easier.
-
-  * Better control over TCP output buffers.
-
-  * Documenation added.
-
-  ++ Bugfixes:
-
-  * Locking issues in buffer management.
-
-  * Bugfixes in the sequential API.
-
-  * IP forwarding could cause memory leakage. This has been fixed.
-
-  ++ Other changes:
-
-  * Directory structure somewhat changed; the core/ tree has been
-    collapsed.
-
-(0.4.2) Changes since version 0.4.1
-
-  ++ New features:
-
-  * Experimental ARP implementation added.
-
-  * Skeleton Ethernet driver added.
-
-  * Experimental BSD socket API library added.
-
-  ++ Bugfixes:
-
-  * In very intense situations, memory leakage could occur. This has
-    been fixed.
-
-  ++ Other changes:
-
-  * Variables named "data" and "code" have been renamed in order to
-    avoid name conflicts in certain compilers.
-
-  * Variable++ have in appliciable cases been translated to ++variable
-    since some compilers generate better code in the latter case.
-
-(0.4.1) Changes since version 0.4
-
-  ++ New features:
-
-  * TCP: Connection attempts time out earlier than data
-    transmissions. Nagle algorithm implemented. Push flag set on the
-    last segment in a burst.
-
-  * UDP: experimental support for UDP-Lite extensions.
-
-  ++ Bugfixes:
-
-  * TCP: out of order segments were in some cases handled incorrectly,
-    and this has now been fixed. Delayed acknowledgements was broken
-    in 0.4, has now been fixed. Binding to an address that is in use
-    now results in an error. Reset connections sometimes hung an
-    application; this has been fixed.
-
-  * Checksum calculation sometimes failed for chained pbufs with odd
-    lengths. This has been fixed.
-
-  * API: a lot of bug fixes in the API. The UDP API has been improved
-    and tested. Error reporting and handling has been
-    improved. Logical flaws and race conditions for incoming TCP
-    connections has been found and removed.
-
-  * Memory manager: alignment issues. Reallocating memory sometimes
-    failed, this has been fixed.
-
-  * Generic library: bcopy was flawed and has been fixed.
-
-  ++ Other changes:
-
-  * API: all datatypes has been changed from generic ones such as
-    ints, to specified ones such as u16_t. Functions that return
-    errors now have the correct type (err_t).
-
-  * General: A lot of code cleaned up and debugging code removed. Many
-    portability issues have been fixed.
-
-  * The license was changed; the advertising clause was removed.
-
-  * C64 port added.
-
-  * Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
-    Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
-    fixing bugs!
-
-(0.4) Changes since version 0.3.1
-
-  * Memory management has been radically changed; instead of
-    allocating memory from a shared heap, memory for objects that are
-    rapidly allocated and deallocated is now kept in pools. Allocation
-    and deallocation from those memory pools is very fast. The shared
-    heap is still present but is used less frequently.
-
-  * The memory, memory pool, and packet buffer subsystems now support
-    4-, 2-, or 1-byte alignment.
-
-  * "Out of memory" situations are handled in a more robust way.
-
-  * Stack usage has been reduced.
-
-  * Easier configuration of lwIP parameters such as memory usage,
-    TTLs, statistics gathering, etc. All configuration parameters are
-    now kept in a single header file "lwipopts.h".
-
-  * The directory structure has been changed slightly so that all
-    architecture specific files are kept under the src/arch
-    hierarchy.
-
-  * Error propagation has been improved, both in the protocol modules
-    and in the API.
-
-  * The code for the RTXC architecture has been implemented, tested
-    and put to use.
-
-  * Bugs have been found and corrected in the TCP, UDP, IP, API, and
-    the Internet checksum modules.
-
-  * Bugs related to porting between a 32-bit and a 16-bit architecture
-    have been found and corrected.
-
-  * The license has been changed slightly to conform more with the
-    original BSD license, including the advertisement clause.
-
-(0.3.1) Changes since version 0.3
-
-  * Fix of a fatal bug in the buffer management. Pbufs with allocated
-    RAM never returned the RAM when the pbuf was deallocated.
-
-  * TCP congestion control, window updates and retransmissions did not
-    work correctly. This has now been fixed.
-
-  * Bugfixes in the API.
-
-(0.3) Changes since version 0.2
-
-  * New and improved directory structure. All include files are now
-    kept in a dedicated include/ directory.
-
-  * The API now has proper error handling. A new function,
-    netconn_err(), now returns an error code for the connection in
-    case of errors.
-
-  * Improvements in the memory management subsystem. The system now
-    keeps a pointer to the lowest free memory block. A new function,
-    mem_malloc2() tries to allocate memory once, and if it fails tries
-    to free some memory and retry the allocation.
-
-  * Much testing has been done with limited memory
-    configurations. lwIP now does a better job when overloaded.
-
-  * Some bugfixes and improvements to the buffer (pbuf) subsystem.
-
-  * Many bugfixes in the TCP code:
-
-    - Fixed a bug in tcp_close().
-
-    - The TCP receive window was incorrectly closed when out of
-      sequence segments was received. This has been fixed.
-
-    - Connections are now timed-out of the FIN-WAIT-2 state.
-
-    - The initial congestion window could in some cases be too
-      large. This has been fixed.
-
-    - The retransmission queue could in some cases be screwed up. This
-      has been fixed.
-
-    - TCP RST flag now handled correctly.
-
-    - Out of sequence data was in some cases never delivered to the
-      application. This has been fixed.
-
-    - Retransmitted segments now contain the correct acknowledgment
-      number and advertised window.
-
-    - TCP retransmission timeout backoffs are not correctly computed
-      (ala BSD). After a number of retransmissions, TCP now gives up
-      the connection.
-
-  * TCP connections now are kept on three lists, one for active
-    connections, one for listening connections, and one for
-    connections that are in TIME-WAIT. This greatly speeds up the fast
-    timeout processing for sending delayed ACKs.
-
-  * TCP now provides proper feedback to the application when a
-    connection has been successfully set up.
-
-  * More comments have been added to the code. The code has also been
-    somewhat cleaned up.
-
-(0.2) Initial public release.

-INTRODUCTION
-
-lwIP is a small independent implementation of the TCP/IP protocol
-suite that has been developed by Adam Dunkels at the Computer and
-Networks Architectures (CNA) lab at the Swedish Institute of Computer
-Science (SICS).
-
-The focus of the lwIP TCP/IP implementation is to reduce the RAM usage
-while still having a full scale TCP. This making lwIP suitable for use
-in embedded systems with tens of kilobytes of free RAM and room for
-around 40 kilobytes of code ROM.
-
-FEATURES
-
- * IP (Internet Protocol) including packet forwarding over multiple
-   network interfaces
- * ICMP (Internet Control Message Protocol) for network maintenance
-   and debugging
- * UDP (User Datagram Protocol) including experimental UDP-lite
-   extensions
- * TCP (Transmission Control Protocol) with congestion control, RTT
-   estimation and fast recovery/fast retransmit
- * Specialized API for enhanced performance
- * Optional Berkeley socket API
-
-LICENSE
-
-lwIP is freely available under a BSD license.
-
-DEVELOPMENT
-
-lwIP has grown into an excellent TCP/IP stack for embedded devices,
-and developers using the stack often submit bug fixes, improvements,
-and additions to the stack to further increase its usefulness.
-
-Development of lwIP is hosted on Savannah, a central point for
-software development, maintenance and distribution. Everyone can
-help improve lwIP by use of Savannah's interface, CVS and the
-mailing list. A core team of developers will commit changes to the
-CVS source tree.
-
-The lwIP TCP/IP stack is maintained in the 'lwip' CVS module and
-contributions (such as platform ports) are in the 'contrib' module.
-
-See doc/savannah.txt for details on CVS server access for users and
-developers.
-
-Last night's CVS tar ball can be downloaded from:
-  http://savannah.gnu.org/cvs.backups/lwip.tar.gz [CHANGED - NEEDS FIXING]
-
-The current CVS trees are web-browsable:
-  http://savannah.nongnu.org/cgi-bin/viewcvs/lwip/lwip/
-  http://savannah.nongnu.org/cgi-bin/viewcvs/lwip/contrib/
-
-Submit patches and bugs via the lwIP project page:
-  http://savannah.nongnu.org/projects/lwip/
-
-
-DOCUMENTATION
-
-The original out-dated homepage of lwIP and Adam Dunkels' papers on
-lwIP are at the official lwIP home page:
-  http://www.sics.se/~adam/lwip/
-
-Self documentation of the source code is regularly extracted from the
-current CVS sources and is available from this web page:
-  http://www.nongnu.org/lwip/
-
-Reading Adam's papers, the files in docs/, browsing the source code
-documentation and browsing the mailing list archives is a good way to
-become familiar with the design of lwIP.

-1 Introduction
-
-This document describes some guidelines for people participating
-in lwIP development.
-
-2 How to contribute to lwIP
-
-Here is a short list of suggestions to anybody working with lwIP and 
-trying to contribute bug reports, fixes, enhancements, platform ports etc.
-First of all as you may already know lwIP is a volunteer project so feedback
-to fixes or questions might often come late. Hopefully the bug and patch tracking 
-features of Savannah help us not lose users' input.
-
-2.1 Source code style:
-
-1. do not use tabs.
-2. indentation is two spaces per level (i.e. per tab).
-3. end debug messages with a trailing newline (\n).
-4. one space between keyword and opening bracket.
-5. no space between function and opening bracket.
-6. one space and no newline before opening curly braces of a block.
-7. closing curly brace on a single line.
-8. spaces surrounding assignment and comparisons.
-9. use current source code style as further reference.
-
-2.2 Source code documentation style:
-
-1. JavaDoc compliant and Doxygen compatible.
-2. Function documentation above functions in .c files, not .h files.
-   (This forces you to synchronize documentation and implementation.)
-3. Use current documentation style as further reference.
- 
-2.3 Bug reports and patches:
-
-1. Make sure you are reporting bugs or send patches against the latest
-   sources. (From the latest release and/or the current CVS sources.)
-2. If you think you found a bug make sure it's not already filed in the
-   bugtracker at Savannah.
-3. If you have a fix put the patch on Savannah. If it is a patch that affects
-   both core and arch specific stuff please separate them so that the core can
-   be applied separately while leaving the other patch 'open'. The prefered way
-   is to NOT touch archs you can't test and let maintainers take care of them.
-   This is a good way to see if they are used at all - the same goes for unix
-   netifs except tapif.
-4. Do not file a bug and post a fix to it to the patch area. Either a bug report
-   or a patch will be enough.
-   If you correct an existing bug then attach the patch to the bug rather than creating a new entry in the patch area.
-5. Trivial patches (compiler warning, indentation and spelling fixes or anything obvious which takes a line or two)
-   can go to the lwip-users list. This is still the fastest way of interaction and the list is not so crowded
-   as to allow for loss of fixes. Putting bugs on Savannah and subsequently closing them is too much an overhead
-   for reporting a compiler warning fix.
-6. Patches should be specific to a single change or to related changes.Do not mix bugfixes with spelling and other
-   trivial fixes unless the bugfix is trivial too.Do not reorganize code and rename identifiers in the same patch you
-   change behaviour if not necessary.A patch is easier to read and understand if it's to the point and short than
-   if it's not to the point and long :) so the chances for it to be applied are greater. 
-
-2.4 Platform porters:
-
-1. If you have ported lwIP to a platform (an OS, a uC/processor or a combination of these) and
-   you think it could benefit others[1] you might want discuss this on the mailing list. You
-   can also ask for CVS access to submit and maintain your port in the contrib CVS module.

-Raw TCP/IP interface for lwIP
-
-Authors: Adam Dunkels, Leon Woestenberg, Christiaan Simons
-
-lwIP provides two Application Program's Interfaces (APIs) for programs
-to use for communication with the TCP/IP code:
-* low-level "core" / "callback" or "raw" API.
-* higher-level "sequential" API.
-
-The sequential API provides a way for ordinary, sequential, programs
-to use the lwIP stack. It is quite similar to the BSD socket API. The
-model of execution is based on the blocking open-read-write-close
-paradigm. Since the TCP/IP stack is event based by nature, the TCP/IP
-code and the application program must reside in different execution
-contexts (threads).
-
-** The remainder of this document discusses the "raw" API. **
-
-The raw TCP/IP interface allows the application program to integrate
-better with the TCP/IP code. Program execution is event based by
-having callback functions being called from within the TCP/IP
-code. The TCP/IP code and the application program both run in the same
-thread. The sequential API has a much higher overhead and is not very
-well suited for small systems since it forces a multithreaded paradigm
-on the application.
-
-The raw TCP/IP interface is not only faster in terms of code execution
-time but is also less memory intensive. The drawback is that program
-development is somewhat harder and application programs written for
-the raw TCP/IP interface are more difficult to understand. Still, this
-is the preferred way of writing applications that should be small in
-code size and memory usage.
-
-Both APIs can be used simultaneously by different application
-programs. In fact, the sequential API is implemented as an application
-program using the raw TCP/IP interface.
-
---- Callbacks
-
-Program execution is driven by callbacks. Each callback is an ordinary
-C function that is called from within the TCP/IP code. Every callback
-function is passed the current TCP or UDP connection state as an
-argument. Also, in order to be able to keep program specific state,
-the callback functions are called with a program specified argument
-that is independent of the TCP/IP state.
-
-The function for setting the application connection state is:
-
-- void tcp_arg(struct tcp_pcb *pcb, void *arg)
-
-  Specifies the program specific state that should be passed to all
-  other callback functions. The "pcb" argument is the current TCP
-  connection control block, and the "arg" argument is the argument
-  that will be passed to the callbacks.
-
-  
---- TCP connection setup
-
-The functions used for setting up connections is similar to that of
-the sequential API and of the BSD socket API. A new TCP connection
-identifier (i.e., a protocol control block - PCB) is created with the
-tcp_new() function. This PCB can then be either set to listen for new
-incoming connections or be explicitly connected to another host.
-
-- struct tcp_pcb *tcp_new(void)
-
-  Creates a new connection identifier (PCB). If memory is not
-  available for creating the new pcb, NULL is returned.
-
-- err_t tcp_bind(struct tcp_pcb *pcb, struct ip_addr *ipaddr,
-                 u16_t port)
-
-  Binds the pcb to a local IP address and port number. The IP address
-  can be specified as IP_ADDR_ANY in order to bind the connection to
-  all local IP addresses.
-
-  If another connection is bound to the same port, the function will
-  return ERR_USE, otherwise ERR_OK is returned.
-
-- struct tcp_pcb *tcp_listen(struct tcp_pcb *pcb)
-
-  Commands a pcb to start listening for incoming connections. When an
-  incoming connection is accepted, the function specified with the
-  tcp_accept() function will be called. The pcb will have to be bound
-  to a local port with the tcp_bind() function.
-
-  The tcp_listen() function returns a new connection identifier, and
-  the one passed as an argument to the function will be
-  deallocated. The reason for this behavior is that less memory is
-  needed for a connection that is listening, so tcp_listen() will
-  reclaim the memory needed for the original connection and allocate a
-  new smaller memory block for the listening connection.
-
-  tcp_listen() may return NULL if no memory was available for the
-  listening connection. If so, the memory associated with the pcb
-  passed as an argument to tcp_listen() will not be deallocated.
-
-- void tcp_accept(struct tcp_pcb *pcb,
-                  err_t (* accept)(void *arg, struct tcp_pcb *newpcb,
-                                   err_t err))
-
-  Specified the callback function that should be called when a new
-  connection arrives on a listening connection.
-      
-- err_t tcp_connect(struct tcp_pcb *pcb, struct ip_addr *ipaddr,
-                    u16_t port, err_t (* connected)(void *arg,
-                                                    struct tcp_pcb *tpcb,
-                                                    err_t err));
-
-  Sets up the pcb to connect to the remote host and sends the
-  initial SYN segment which opens the connection. 
-
-  The tcp_connect() function returns immediately; it does not wait for
-  the connection to be properly setup. Instead, it will call the
-  function specified as the fourth argument (the "connected" argument)
-  when the connection is established. If the connection could not be
-  properly established, either because the other host refused the
-  connection or because the other host didn't answer, the "connected"
-  function will be called with an the "err" argument set accordingly.
-
-  The tcp_connect() function can return ERR_MEM if no memory is
-  available for enqueueing the SYN segment. If the SYN indeed was
-  enqueued successfully, the tcp_connect() function returns ERR_OK.
-
-  
---- Sending TCP data
-
-TCP data is sent by enqueueing the data with a call to
-tcp_write(). When the data is successfully transmitted to the remote
-host, the application will be notified with a call to a specified
-callback function.
-
-- err_t tcp_write(struct tcp_pcb *pcb, void *dataptr, u16_t len,
-                  u8_t copy)
-
-  Enqueues the data pointed to by the argument dataptr. The length of
-  the data is passed as the len parameter. The copy argument is either
-  0 or 1 and indicates whether the new memory should be allocated for
-  the data to be copied into. If the argument is 0, no new memory
-  should be allocated and the data should only be referenced by
-  pointer.
-
-  The tcp_write() function will fail and return ERR_MEM if the length
-  of the data exceeds the current send buffer size or if the length of
-  the queue of outgoing segment is larger than the upper limit defined
-  in lwipopts.h. The number of bytes available in the output queue can
-  be retrieved with the tcp_sndbuf() function.
-
-  The proper way to use this function is to call the function with at
-  most tcp_sndbuf() bytes of data. If the function returns ERR_MEM,
-  the application should wait until some of the currently enqueued
-  data has been successfully received by the other host and try again.
-
-- void tcp_sent(struct tcp_pcb *pcb,
-                err_t (* sent)(void *arg, struct tcp_pcb *tpcb,
-		               u16_t len))
-
-  Specifies the callback function that should be called when data has
-  successfully been received (i.e., acknowledged) by the remote
-  host. The len argument passed to the callback function gives the
-  amount bytes that was acknowledged by the last acknowledgment.
-
-  
---- Receiving TCP data
-
-TCP data reception is callback based - an application specified
-callback function is called when new data arrives. When the
-application has taken the data, it has to call the tcp_recved()
-function to indicate that TCP can advertise increase the receive
-window.
-
-- void tcp_recv(struct tcp_pcb *pcb,
-                err_t (* recv)(void *arg, struct tcp_pcb *tpcb,
-                               struct pbuf *p, err_t err))
-
-  Sets the callback function that will be called when new data
-  arrives. The callback function will be passed a NULL pbuf to
-  indicate that the remote host has closed the connection.
-
-- void tcp_recved(struct tcp_pcb *pcb, u16_t len)
-
-  Must be called when the application has received the data. The len
-  argument indicates the length of the received data.
-    
-
---- Application polling
-
-When a connection is idle (i.e., no data is either transmitted or
-received), lwIP will repeatedly poll the application by calling a
-specified callback function. This can be used either as a watchdog
-timer for killing connections that have stayed idle for too long, or
-as a method of waiting for memory to become available. For instance,
-if a call to tcp_write() has failed because memory wasn't available,
-the application may use the polling functionality to call tcp_write()
-again when the connection has been idle for a while.
-
-- void tcp_poll(struct tcp_pcb *pcb, u8_t interval,
-                err_t (* poll)(void *arg, struct tcp_pcb *tpcb))
-
-  Specifies the polling interval and the callback function that should
-  be called to poll the application. The interval is specified in
-  number of TCP coarse grained timer shots, which typically occurs
-  twice a second. An interval of 10 means that the application would
-  be polled every 5 seconds.
-
-
---- Closing and aborting connections
-
-- err_t tcp_close(struct tcp_pcb *pcb)
-
-  Closes the connection. The function may return ERR_MEM if no memory
-  was available for closing the connection. If so, the application
-  should wait and try again either by using the acknowledgment
-  callback or the polling functionality. If the close succeeds, the
-  function returns ERR_OK.
-
-  The pcb is deallocated by the TCP code after a call to tcp_close(). 
-
-- void tcp_abort(struct tcp_pcb *pcb)
-
-  Aborts the connection by sending a RST (reset) segment to the remote
-  host. The pcb is deallocated. This function never fails.
-
-If a connection is aborted because of an error, the application is
-alerted of this event by the err callback. Errors that might abort a
-connection are when there is a shortage of memory. The callback
-function to be called is set using the tcp_err() function.
-
-- void tcp_err(struct tcp_pcb *pcb, void (* err)(void *arg,
-	       err_t err))
-
-  The error callback function does not get the pcb passed to it as a
-  parameter since the pcb may already have been deallocated.
-
-
---- Lower layer TCP interface
-
-TCP provides a simple interface to the lower layers of the
-system. During system initialization, the function tcp_init() has
-to be called before any other TCP function is called. When the system
-is running, the two timer functions tcp_fasttmr() and tcp_slowtmr()
-must be called with regular intervals. The tcp_fasttmr() should be
-called every TCP_FAST_INTERVAL milliseconds (defined in tcp.h) and
-tcp_slowtmr() should be called every TCP_SLOW_INTERVAL milliseconds. 
-
-
---- UDP interface
-
-The UDP interface is similar to that of TCP, but due to the lower
-level of complexity of UDP, the interface is significantly simpler.
-
-- struct udp_pcb *udp_new(void)
-
-  Creates a new UDP pcb which can be used for UDP communication. The
-  pcb is not active until it has either been bound to a local address
-  or connected to a remote address.
-
-- void udp_remove(struct udp_pcb *pcb)
-
-  Removes and deallocates the pcb.  
-  
-- err_t udp_bind(struct udp_pcb *pcb, struct ip_addr *ipaddr,
-                 u16_t port)
-
-  Binds the pcb to a local address. The IP-address argument "ipaddr"
-  can be IP_ADDR_ANY to indicate that it should listen to any local IP
-  address. The function currently always return ERR_OK.
-
-- err_t udp_connect(struct udp_pcb *pcb, struct ip_addr *ipaddr,
-                    u16_t port)
-
-  Sets the remote end of the pcb. This function does not generate any
-  network traffic, but only set the remote address of the pcb.
-
-- err_t udp_disconnect(struct udp_pcb *pcb)
-
-  Remove the remote end of the pcb. This function does not generate
-  any network traffic, but only removes the remote address of the pcb.
-
-- err_t udp_send(struct udp_pcb *pcb, struct pbuf *p)
-
-  Sends the pbuf p. The pbuf is not deallocated.
-
-- void udp_recv(struct udp_pcb *pcb,
-                void (* recv)(void *arg, struct udp_pcb *upcb,
-                                         struct pbuf *p,
-                                         struct ip_addr *addr,
-                                         u16_t port),
-                              void *recv_arg)
-
-  Specifies a callback function that should be called when a UDP
-  datagram is received.
-  
-
---- System initalization
-
-A truly complete and generic sequence for initializing the lwip stack
-cannot be given because it depends on the build configuration (lwipopts.h)
-and additional initializations for your runtime environment (e.g. timers).
-
-We can give you some idea on how to proceed when using the raw API.
-We assume a configuration using a single Ethernet netif and the
-UDP and TCP transport layers, IPv4 and the DHCP client.
-
-Call these functions in the order of appearance:
-
-- stats_init()
-
-  Clears the structure where runtime statistics are gathered.
-
-- sys_init()
-  
-  Not of much use since we set the NO_SYS 1 option in lwipopts.h,
-  to be called for easy configuration changes.
-
-- mem_init()
-
-  Initializes the dynamic memory heap defined by MEM_SIZE.
-
-- memp_init()
-
-  Initializes the memory pools defined by MEMP_NUM_x.
-
-- pbuf_init()
-
-  Initializes the pbuf memory pool defined by PBUF_POOL_SIZE.
-  
-- etharp_init()
-
-  Initializes the ARP table and queue.
-  Note: you must call etharp_tmr at a 10 second regular interval
-  after this initialization.
-
-- ip_init()
-
-  Doesn't do much, it should be called to handle future changes.
-
-- udp_init()
-
-  Clears the UDP PCB list.
-
-- tcp_init()
-
-  Clears the TCP PCB list and clears some internal TCP timers.
-  Note: you must call tcp_fasttmr() and tcp_slowtmr() at the
-  predefined regular intervals after this initialization. 
-  
-- netif_add(struct netif *netif, struct ip_addr *ipaddr,
-            struct ip_addr *netmask, struct ip_addr *gw,
-            void *state, err_t (* init)(struct netif *netif),
-            err_t (* input)(struct pbuf *p, struct netif *netif))
-
-  Adds your network interface to the netif_list. Allocate a struct
-  netif and pass a pointer to this structure as the first argument.
-  Give pointers to cleared ip_addr structures when using DHCP,
-  or fill them with sane numbers otherwise. The state pointer may be NULL.
-
-  The init function pointer must point to a initialization function for
-  your ethernet netif interface. The following code illustrates it's use.
-  
-  err_t netif_if_init(struct netif *netif)
-  {
-    u8_t i;
-    
-    for(i = 0; i < 6; i++) netif->hwaddr[i] = some_eth_addr[i];
-    init_my_eth_device();
-    return ERR_OK;
-  }
-  
-  The input function pointer must point to the lwip ip_input().
-  
-- netif_set_default(struct netif *netif)
-
-  Registers the default network interface.
-
-- netif_set_up(struct netif *netif)
-
-  When the netif is fully configured this function must be called.
-
-- dhcp_start(struct netif *netif)
-
-  Creates a new DHCP client for this interface on the first call.
-  Note: you must call dhcp_fine_tmr() and dhcp_coarse_tmr() at
-  the predefined regular intervals after starting the client.
-  
-  You can peek in the netif->dhcp struct for the actual DHCP status.
-
-
---- Optimalization hints
-
-The first thing you want to optimize is the lwip_standard_checksum()
-routine from src/core/inet.c. You can override this standard
-function with the #define LWIP_CHKSUM <your_checksum_routine>.
-
-There are C examples given in inet.c or you might want to
-craft an assembly function for this. RFC1071 is a good
-introduction to this subject.
-
-Other significant improvements can be made by supplying
-assembly or inline replacements for htons() and htonl()
-if you're using a little-endian architecture.
-#define LWIP_PLATFORM_BYTESWAP 1
-#define LWIP_PLATFORM_HTONS(x) <your_htons>
-#define LWIP_PLATFORM_HTONL(x) <your_htonl>
-
-Check your network interface driver if it reads at
-a higher speed than the maximum wire-speed. If the
-hardware isn't serviced frequently and fast enough
-buffer overflows are likely to occur.
-
-E.g. when using the cs8900 driver, call cs8900if_service(ethif)
-as frequently as possible. When using an RTOS let the cs8900 interrupt
-wake a high priority task that services your driver using a binary
-semaphore or event flag. Some drivers might allow additional tuning
-to match your application and network.
-
-For a production release it is recommended to set LWIP_STATS to 0.
-Note that speed performance isn't influenced much by simply setting
-high values to the memory options.

-
-
-1 Obtaining lwIP from the CVS repository
-----------------------------------------
-
-To perform an anonymous CVS checkout of the main trunk (this is where
-bug fixes and incremental enhancements occur), do this:
-
-cvs -z3 -d:pserver:anonymous at cvs.sv.gnu.org:/sources/lwip checkout lwip
- 
-Or, obtain a stable branch (updated with bug fixes only) as follows:
-cvs -z3 -d:pserver:anonymous at cvs.sv.gnu.org:/sources/lwip checkout \
-  -r STABLE-0_7 -d lwip-0.7 lwip
-
-Or, obtain a specific (fixed) release as follows:
-cvs -z3 -d:pserver:anonymous at cvs.sv.gnu.org:/sources/lwip checkout \
-  -r STABLE-0_7_0 -d lwip-0.7.0 lwip
-
-3 Committers/developers CVS access using SSH
---------------------------------------------
-
-The Savannah server uses SSH (Secure Shell) protocol 2 authentication and encryption.
-As such, CVS commits to the server occur through a SSH tunnel for project members.
-To create a SSH2 key pair in UNIX-like environments, do this:
-
-ssh-keygen -t dsa
-
-Under Windows, a recommended SSH client is "PuTTY", freely available with good
-documentation and a graphic user interface. Use its key generator.
-
-Now paste the id_dsa.pub contents into your Savannah account public key list. Wait
-a while so that Savannah can update its configuration (This can take minutes).
-
-Try to login using SSH:
-
-ssh -v your_login at cvs.sv.gnu.org
-
-If it tells you:
-
-Authenticating with public key "your_key_name"...
-Server refused to allocate pty
-
-then you could login; Savannah refuses to give you a shell - which is OK, as we
-are allowed to use SSH for CVS only. Now, you should be able to do this:
-
-export CVS_RSH=ssh
-cvs -z3 -d:ext:your_login at cvs.sv.gnu.org:/sources/lwip co lwip
- 
-after which you can edit your local files with bug fixes or new features and
-commit them. Make sure you know what you are doing when using CVS to make
-changes on the repository. If in doubt, ask on the lwip-members mailing list.
-
-(If SSH asks about authenticity of the host, you can check the key
- fingerprint against http://savannah.nongnu.org/cvs/?group=lwip)
-
-
-3 Merging from DEVEL branch to main trunk (stable)
---------------------------------------------------
-
-Merging is a delicate process in CVS and requires the
-following disciplined steps in order to prevent conflicts
-in the future. Conflicts can be hard to solve!
-
-Merging from branch A to branch B requires that the A branch
-has a tag indicating the previous merger. This tag is called
-'merged_from_A_to_B'. After merging, the tag is moved in the
-A branch to remember this merger for future merge actions.
-
-IMPORTANT: AFTER COMMITTING A SUCCESFUL MERGE IN THE
-REPOSITORY, THE TAG MUST BE SET ON THE SOURCE BRANCH OF THE
-MERGE ACTION (REPLACING EXISTING TAGS WITH THE SAME NAME).
-
-Merge all changes in DEVEL since our last merge to main:
-
-In the working copy of the main trunk:
-cvs update -P -jmerged_from_DEVEL_to_main -jDEVEL 
-
-(This will apply the changes between 'merged_from_DEVEL_to_main'
-and 'DEVEL' to your work set of files)
-
-We can now commit the merge result.
-cvs commit -R -m "Merged from DEVEL to main." 
-
-If this worked out OK, we now move the tag in the DEVEL branch
-to this merge point, so we can use this point for future merges:
-
-cvs rtag -F -r DEVEL merged_from_DEVEL_to_main lwip 
-
-4 How to release lwIP
----------------------
-
-First, checkout a clean copy of the branch to be released. Tag this set with
-tag name "STABLE-0_6_3". (I use release number 0.6.3 throughout this example).
-
-Login CVS using pserver authentication, then export a clean copy of the
-tagged tree. Export is similar to a checkout, except that the CVS metadata
-is not created locally. 
-
-export CVS_RSH=ssh
-cvs -z3 -d:pserver:anonymous at cvs.sv.gnu.org:/sources/lwip checkout \
-  -r STABLE-0_6_3 -d lwip-0.6.3 lwip
-
-Archive this directory using tar, gzip'd, bzip2'd and zip'd.
-
-tar czvf lwip-0.6.3.tar.gz lwip-0.6.3
-tar cjvf lwip-0.6.3.tar.bz2 lwip-0.6.3
-zip -r lwip-0.6.3.zip lwip-0.6.3
-
-Now, sign the archives with a detached GPG binary signature as follows:
-
-gpg -b lwip-0.6.3.tar.gz
-gpg -b lwip-0.6.3.tar.bz2
-gpg -b lwip-0.6.3.zip
-
-Upload these files using anonymous FTP:
-ncftp ftp://savannah.gnu.org/incoming/savannah/lwip
-
-ncftp>mput *0.6.3.*
-
-Additionally, you may post a news item on Savannah, like this:
-
-A new 0.6.3 release is now available here:
-http://savannah.nongnu.org/files/?group=lwip&highlight=0.6.3
-
-You will have to submit this via the user News interface, then approve
-this via the Administrator News interface.

-SNMPv1 agent for lwIP
-
-Author: Christiaan Simons
-
-This is a brief introduction how to use and configure the SNMP agent.
-Note the agent uses the raw-API UDP interface so you may also want to
-read rawapi.txt to gain a better understanding of the SNMP message handling.
-
-0 Agent Capabilities
-====================
-
-SNMPv1 per RFC1157
-  This is an old(er) standard but is still widely supported.
-  For SNMPv2c and v3 have a greater complexity and need many
-  more lines of code. IMHO this breaks the idea of "lightweight IP".
-
-  Note the S in SNMP stands for "Simple". Note that "Simple" is
-  relative. SNMP is simple compared to the complex ISO network
-  management protocols CMIP (Common Management Information Protocol)
-  and CMOT (CMip Over Tcp).
-
-MIB II per RFC1213
-  The standard lwIP stack management information base.
-  This is a required MIB, so this is always enabled.
-  When builing lwIP without TCP, the mib-2.tcp group is omitted.
-  The groups EGP, CMOT and transmission are disabled by default.
-  
-  Most mib-2 objects are not writable except:
-  sysName, sysLocation, sysContact, snmpEnableAuthenTraps.
-  Writing to or changing the ARP and IP address and route
-  tables is not possible.
- 
-  Note lwIP has a very limited notion of IP routing. It currently
-  doen't have a route table and doesn't have a notion of the U,G,H flags.
-  Instead lwIP uses the interface list with only one default interface
-  acting as a single gateway interface (G) for the default route.
-
-  The agent returns a "virtual table" with the default route 0.0.0.0
-  for the default interface and network routes (no H) for each
-  network interface in the netif_list.
-  All routes are considered to be up (U).
-
-Loading additional MIBs
-  MIBs can only be added in compile-time, not in run-time.
-  There is no MIB compiler thus additional MIBs must be hand coded.
-
-Large SNMP message support
-  The packet decoding and encoding routines are designed
-  to use pbuf-chains. Larger payloads then the minimum
-  SNMP requirement of 484 octets are supported if the 
-  PBUF_POOL_SIZE and IP_REASS_BUFSIZE are set to match your
-  local requirement.
-
-1 Building the Agent
-====================
-
-First of all you'll need to add the following define
-to your local lwipopts.h:
-
-#define LWIP_SNMP               1
-
-and add the source files in lwip/src/core/snmp
-and some snmp headers in lwip/src/include/lwip to your makefile.
-
-Note you'll might need to adapt you network driver to update
-the mib2 variables for your interface.
-
-2 Running the Agent
-===================
-
-The following function calls must be made in your program to
-actually get the SNMP agent running.
-
-Before starting the agent you should supply pointers
-to non-volatile memory for sysContact, sysLocation,
-and snmpEnableAuthenTraps. You can do this by calling
-
-snmp_set_syscontact()
-snmp_set_syslocation()
-snmp_set_snmpenableauthentraps()
-
-Additionally you may want to set
-
-snmp_set_sysdescr()
-snmp_set_sysobjid() (if you have a private MIB)
-snmp_set_sysname()
-
-Also before starting the agent you need to setup
-one or more trap destinations using these calls:
-
-snmp_trap_dst_enable();
-snmp_trap_dst_ip_set();
-
-In the lwIP initialisation sequence call snmp_init() just after
-the call to udp_init().
-
-Exactly every 10 msec the SNMP uptime timestamp must be updated with
-snmp_inc_sysuptime(). You should call this from a timer interrupt
-or a timer signal handler depending on your runtime environment.
-
-
-3 Private MIBs
-==============
-
-If want to extend the agent with your own private MIB you'll need to
-add the following define to your local lwipopts.h:
-
-#define SNMP_PRIVATE_MIB        1
-
-You must provide the private_mib.h and associated files yourself.
-Note we don't have a "MIB compiler" that generates C source from a MIB,
-so you're required to do some serious coding if you enable this!
-
-Note the lwIP enterprise ID (26381) is assigned to the lwIP project,
-ALL OBJECT IDENTIFIERS LIVING UNDER THIS ID ARE ASSIGNED BY THE lwIP
-MAINTAINERS!
-
-If you need to create your own private MIB you'll need
-to apply for your own enterprise ID with IANA: http://www.iana.org/numbers.html 
-
-You can set it by passing a struct snmp_obj_id to the agent
-using snmp_set_sysobjid(&my_object_id), just before snmp_init().
-
-Note the object identifiers for thes MIB-2 and your private MIB
-tree must be kept in sorted ascending (lexicographical) order.
-This to ensure correct getnext operation.
-
-An example for a private MIB is part of the "minimal Unix" project:
-contrib/ports/unix/proj/minimal/lwip_prvmib.c
-
-The next chapter gives a more detailed description of the
-MIB-2 tree and the optional private MIB.
-
-4 The Gory Details
-==================
-
-4.0 Object identifiers and the MIB tree.
-
-We have three distinct parts for all object identifiers:
-
-The prefix
-  .iso.org.dod.internet
-
-the middle part 
-  .mgmt.mib-2.ip.ipNetToMediaTable.ipNetToMediaEntry.ipNetToMediaPhysAddress
-
-and the index part
-  .1.192.168.0.1
-
-Objects located above the .internet hierarchy aren't supported.
-Currently only the .mgmt sub-tree is available and
-when the SNMP_PRIVATE_MIB is enabled the .private tree
-becomes available too.
-
-Object identifiers from incoming requests are checked
-for a matching prefix, middle part and index part
-or are expanded(*) for GetNext requests with short
-or inexisting names in the request.
-(* we call this "expansion" but this also
-resembles the "auto-completion" operation)
-
-The middle part is usually located in ROM (const)
-to preserve precious RAM on small microcontrollers.
-However RAM location is possible for an dynamically
-changing private tree.
-
-The index part is handled by functions which in
-turn use dynamically allocated index trees from RAM.
-These trees are updated by e.g. the etharp code
-when new entries are made or removed form the ARP cache.
-

-sys_arch interface for lwIP 0.6++
-
-Author: Adam Dunkels
-
-The operating system emulation layer provides a common interface
-between the lwIP code and the underlying operating system kernel. The
-general idea is that porting lwIP to new architectures requires only
-small changes to a few header files and a new sys_arch
-implementation. It is also possible to do a sys_arch implementation
-that does not rely on any underlying operating system.
-
-The sys_arch provides semaphores and mailboxes to lwIP. For the full
-lwIP functionality, multiple threads support can be implemented in the
-sys_arch, but this is not required for the basic lwIP
-functionality. Previous versions of lwIP required the sys_arch to
-implement timer scheduling as well but as of lwIP 0.5 this is
-implemented in a higher layer.
-
-In addition to the source file providing the functionality of sys_arch,
-the OS emulation layer must provide several header files defining
-macros used throughout lwip.  The files required and the macros they
-must define are listed below the sys_arch description.
-
-Semaphores can be either counting or binary - lwIP works with both
-kinds. Mailboxes are used for message passing and can be implemented
-either as a queue which allows multiple messages to be posted to a
-mailbox, or as a rendez-vous point where only one message can be
-posted at a time. lwIP works with both kinds, but the former type will
-be more efficient. A message in a mailbox is just a pointer, nothing
-more. 
-
-Semaphores are represented by the type "sys_sem_t" which is typedef'd
-in the sys_arch.h file. Mailboxes are equivalently represented by the
-type "sys_mbox_t". lwIP does not place any restrictions on how
-sys_sem_t or sys_mbox_t are represented internally.
-
-The following functions must be implemented by the sys_arch:
-
-- void sys_init(void)
-
-  Is called to initialize the sys_arch layer.
-
-- sys_sem_t sys_sem_new(u8_t count)
-
-  Creates and returns a new semaphore. The "count" argument specifies
-  the initial state of the semaphore.
-
-- void sys_sem_free(sys_sem_t sem)
-
-  Deallocates a semaphore.
-
-- void sys_sem_signal(sys_sem_t sem)
-
-  Signals a semaphore.
-
-- u32_t sys_arch_sem_wait(sys_sem_t sem, u32_t timeout)
-
-  Blocks the thread while waiting for the semaphore to be
-  signaled. If the "timeout" argument is non-zero, the thread should
-  only be blocked for the specified time (measured in
-  milliseconds).
-
-  If the timeout argument is non-zero, the return value is the number of
-  milliseconds spent waiting for the semaphore to be signaled. If the
-  semaphore wasn't signaled within the specified time, the return value is
-  SYS_ARCH_TIMEOUT. If the thread didn't have to wait for the semaphore
-  (i.e., it was already signaled), the function may return zero.
-
-  Notice that lwIP implements a function with a similar name,
-  sys_sem_wait(), that uses the sys_arch_sem_wait() function.
-
-- sys_mbox_t sys_mbox_new(void)
-
-  Creates an empty mailbox.
-
-- void sys_mbox_free(sys_mbox_t mbox)
-
-  Deallocates a mailbox. If there are messages still present in the
-  mailbox when the mailbox is deallocated, it is an indication of a
-  programming error in lwIP and the developer should be notified.
-
-- void sys_mbox_post(sys_mbox_t mbox, void *msg)
-
-  Posts the "msg" to the mailbox.
-
-- u32_t sys_arch_mbox_fetch(sys_mbox_t mbox, void **msg, u32_t timeout)
-
-  Blocks the thread until a message arrives in the mailbox, but does
-  not block the thread longer than "timeout" milliseconds (similar to
-  the sys_arch_sem_wait() function). The "msg" argument is a result
-  parameter that is set by the function (i.e., by doing "*msg =
-  ptr"). The "msg" parameter maybe NULL to indicate that the message
-  should be dropped.
-
-  The return values are the same as for the sys_arch_sem_wait() function:
-  Number of milliseconds spent waiting or SYS_ARCH_TIMEOUT if there was a
-  timeout.
-
-  Note that a function with a similar name, sys_mbox_fetch(), is
-  implemented by lwIP. 
-  
-- struct sys_timeouts *sys_arch_timeouts(void)
-
-  Returns a pointer to the per-thread sys_timeouts structure. In lwIP,
-  each thread has a list of timeouts which is repressented as a linked
-  list of sys_timeout structures. The sys_timeouts structure holds a
-  pointer to a linked list of timeouts. This function is called by
-  the lwIP timeout scheduler and must not return a NULL value. 
-
-  In a single threadd sys_arch implementation, this function will
-  simply return a pointer to a global sys_timeouts variable stored in
-  the sys_arch module.
-  
-If threads are supported by the underlying operating system and if
-such functionality is needed in lwIP, the following function will have
-to be implemented as well:
-
-- sys_thread_t sys_thread_new(void (* thread)(void *arg), void *arg, int prio)
-
-  Starts a new thread with priority "prio" that will begin its execution in the
-  function "thread()". The "arg" argument will be passed as an argument to the
-  thread() function. The id of the new thread is returned. Both the id and
-  the priority are system dependent.
-
-- sys_prot_t sys_arch_protect(void)
-
-  This optional function does a "fast" critical region protection and returns
-  the previous protection level. This function is only called during very short
-  critical regions. An embedded system which supports ISR-based drivers might
-  want to implement this function by disabling interrupts. Task-based systems
-  might want to implement this by using a mutex or disabling tasking. This
-  function should support recursive calls from the same task or interrupt. In
-  other words, sys_arch_protect() could be called while already protected. In
-  that case the return value indicates that it is already protected.
-
-  sys_arch_protect() is only required if your port is supporting an operating
-  system.
-
-- void sys_arch_unprotect(sys_prot_t pval)
-
-  This optional function does a "fast" set of critical region protection to the
-  value specified by pval. See the documentation for sys_arch_protect() for
-  more information. This function is only required if your port is supporting
-  an operating system.
-
-Note:
-
-Be carefull with using mem_malloc() in sys_arch. When malloc() refers to
-mem_malloc() you can run into a circular function call problem. In mem.c
-mem_init() tries to allcate a semaphore using mem_malloc, which of course
-can't be performed when sys_arch uses mem_malloc.
-
--------------------------------------------------------------------------------
-Additional files required for the "OS support" emulation layer:
--------------------------------------------------------------------------------
-
-cc.h       - Architecture environment, some compiler specific, some
-             environment specific (probably should move env stuff 
-             to sys_arch.h.)
-
-  Typedefs for the types used by lwip -
-    u8_t, s8_t, u16_t, s16_t, u32_t, s32_t, mem_ptr_t
-
-  Compiler hints for packing lwip's structures -
-    PACK_STRUCT_FIELD(x)
-    PACK_STRUCT_STRUCT
-    PACK_STRUCT_BEGIN
-    PACK_STRUCT_END
-
-  Platform specific diagnostic output -
-    LWIP_PLATFORM_DIAG(x)    - non-fatal, print a message.
-    LWIP_PLATFORM_ASSERT(x)  - fatal, print message and abandon execution.
-
-  "lightweight" synchronization mechanisms -
-    SYS_ARCH_DECL_PROTECT(x) - declare a protection state variable.
-    SYS_ARCH_PROTECT(x)      - enter protection mode.
-    SYS_ARCH_UNPROTECT(x)    - leave protection mode.
-
-  If the compiler does not provide memset() this file must include a
-  definition of it, or include a file which defines it.
-
-  This file must either include a system-local <errno.h> which defines
-  the standard *nix error codes, or it should #define LWIP_PROVIDE_ERRNO
-  to make lwip/arch.h define the codes which are used throughout.
-
-
-perf.h     - Architecture specific performance measurement.
-  Measurement calls made throughout lwip, these can be defined to nothing.
-    PERF_START               - start measuring something.
-    PERF_STOP(x)             - stop measuring something, and record the result.
-
-sys_arch.h - Tied to sys_arch.c
-
-  Arch dependent types for the following objects:
-    sys_sem_t, sys_mbox_t, sys_thread_t,
-  And, optionally:
-    sys_prot_t
-
-  Defines to set vars of sys_mbox_t and sys_sem_t to NULL.
-    SYS_MBOX_NULL NULL
-    SYS_SEM_NULL NULL

- * This is a DHCP client for the lwIP TCP/IP stack. It aims to conform
- * with RFC 2131 and RFC 2132.
- *
- * TODO:
- * - Proper parsing of DHCP messages exploiting file/sname field overloading.
- * - Add JavaDoc style documentation (API, internals).
- * - Support for interfaces other than Ethernet (SLIP, PPP, ...)
- *
- * Please coordinate changes and requests with Leon Woestenberg
- * <leon.woestenberg at gmx.net>
- *
- * Integration with your code:
- *
- * In lwip/dhcp.h
- * #define DHCP_COARSE_TIMER_SECS (recommended 60 which is a minute)
- * #define DHCP_FINE_TIMER_MSECS (recommended 500 which equals TCP coarse timer)
- *
- * Then have your application call dhcp_coarse_tmr() and
- * dhcp_fine_tmr() on the defined intervals.
- *
- * dhcp_start(struct netif *netif);
- * starts a DHCP client instance which configures the interface by
- * obtaining an IP address lease and maintaining it.
- *
- * Use dhcp_release(netif) to end the lease and use dhcp_stop(netif)
- * to remove the DHCP client.

-/**
- * @file
- * Packet buffer management
- *
- * Packets are built from the pbuf data structure. It supports dynamic
- * memory allocation for packet contents or can reference externally
- * managed packet contents both in RAM and ROM. Quick allocation for
- * incoming packets is provided through pools with fixed sized pbufs.
- *
- * A packet may span over multiple pbufs, chained as a singly linked
- * list. This is called a "pbuf chain".
- *
- * Multiple packets may be queued, also using this singly linked list.
- * This is called a "packet queue".
- * 
- * So, a packet queue consists of one or more pbuf chains, each of
- * which consist of one or more pbufs. Currently, queues are only
- * supported in a limited section of lwIP, this is the etharp queueing
- * code. Outside of this section no packet queues are supported yet.
- * 
- * The differences between a pbuf chain and a packet queue are very
- * precise but subtle. 
- *
- * The last pbuf of a packet has a ->tot_len field that equals the
- * ->len field. It can be found by traversing the list. If the last
- * pbuf of a packet has a ->next field other than NULL, more packets
- * are on the queue.
- *
- * Therefore, looping through a pbuf of a single packet, has an
- * loop end condition (tot_len == p->len), NOT (next == NULL).

- * Allocates a pbuf of the given type (possibly a chain for PBUF_POOL type).
- *
- * The actual memory allocated for the pbuf is determined by the
- * layer at which the pbuf is allocated and the requested size
- * (from the size parameter).
- *
- * @param flag this parameter decides how and where the pbuf
- * should be allocated as follows:
- *
- * - PBUF_RAM: buffer memory for pbuf is allocated as one large
- *             chunk. This includes protocol headers as well.
- * - PBUF_ROM: no buffer memory is allocated for the pbuf, even for
- *             protocol headers. Additional headers must be prepended
- *             by allocating another pbuf and chain in to the front of
- *             the ROM pbuf. It is assumed that the memory used is really
- *             similar to ROM in that it is immutable and will not be
- *             changed. Memory which is dynamic should generally not
- *             be attached to PBUF_ROM pbufs. Use PBUF_REF instead.
- * - PBUF_REF: no buffer memory is allocated for the pbuf, even for
- *             protocol headers. It is assumed that the pbuf is only
- *             being used in a single thread. If the pbuf gets queued,
- *             then pbuf_take should be called to copy the buffer.
- * - PBUF_POOL: the pbuf is allocated as a pbuf chain, with pbufs from
- *              the pbuf pool that is allocated during pbuf_init().
- *
- * @return the allocated pbuf. If multiple pbufs where allocated, this
- * is the first pbuf of a pbuf chain.

-/**
- * @file
- * SNMP output message processing (RFC1157).
- *
- * Output responses and traps are build in two passes:
- *
- * Pass 0: iterate over the output message backwards to determine encoding lengths
- * Pass 1: the actual forward encoding of internal form into ASN1
- *
- * The single-pass encoding method described by Comer & Stevens
- * requires extra buffer space and copying for reversal of the packet.
- * The buffer requirement can be prohibitively large for big payloads
- * (>= 484) therefore we use the two encoding passes.

-    now is in sequence (i.e., if rcv_nxt >= ooseq->seqno). If
-    rcv_nxt > ooseq->seqno, we must trim the first edge of the

-etharp.c
-          Implements the ARP (Address Resolution Protocol) over
-          Ethernet. The code in this file should be used together with
-          Ethernet device drivers. Note that this module has been
-          largely made Ethernet independent so you should be able to
-          adapt this for other link layers (such as Firewire).
-
-ethernetif.c
-          An example of how an Ethernet device driver could look. This
-          file can be used as a "skeleton" for developing new Ethernet
-          network device drivers. It uses the etharp.c ARP code.
-
-loopif.c
-          An example network interface that shows how a "loopback"
-          interface would work. This is not really intended for actual
-          use, but as a very basic example of how initialization and
-          output functions work.
-
-slipif.c
-          A generic implementation of the SLIP (Serial Line IP)
-          protocol. It requires a sio (serial I/O) module to work.

- *
- *   Implemented LANManager type password response to MS-CHAP challenges.

- * Compressed packet format:
- *
- * The first octet contains the packet type (top 3 bits), TCP
- * 'push' bit, and flags that indicate which of the 4 TCP sequence
- * numbers have changed (bottom 5 bits).  The next octet is a
- * conversation number that associates a saved IP/TCP header with
- * the compressed packet.  The next two octets are the TCP checksum
- * from the original datagram.  The next 0 to 15 octets are
- * sequence number changes, one change per bit set in the header
- * (there may be no changes and there are two special cases where
- * the receiver implicitly knows what changed -- see below).
- * 
- * There are 5 numbers which can change (they are always inserted
- * in the following order): TCP urgent pointer, window,
- * acknowlegement, sequence number and IP ID.  (The urgent pointer
- * is different from the others in that its value is sent, not the
- * change in value.)  Since typical use of SLIP links is biased
- * toward small packets (see comments on MTU/MSS below), changes
- * use a variable length coding with one octet for numbers in the
- * range 1 - 255 and 3 octets (0, MSB, LSB) for numbers in the
- * range 256 - 65535 or 0.  (If the change in sequence number or
- * ack is more than 65535, an uncompressed packet is sent.)

- * Packet types (must not conflict with IP protocol version)
- *
- * The top nibble of the first octet is the packet type.  There are
- * three possible types: IP (not proto TCP or tcp with one of the
- * control flags set); uncompressed TCP (a normal IP/TCP packet but
- * with the 8-bit protocol field replaced by an 8-bit connection id --
- * this type of packet syncs the sender & receiver); and compressed
- * TCP (described above).
- *
- * LSB of 4-bit field is TCP "PUSH" bit (a worthless anachronism) and
- * is logically part of the 4-bit "changes" field that follows.  Top
- * three bits are actual packet type.  For backward compatibility
- * and in the interest of conserving bits, numbers are chosen so the
- * IP protocol version number (4) which normally appears in this nibble
- * means "IP packet".

+      responsible for actions which require system level privileges.
+
+      Each guest session keeps track of the guest directories and files that
+      it opened as well as guest processes it has created.  To work on guest
+      files or directories a guest session offers methods to open or create
+      such objects (see <link to="IGuestSession::fileOpen"/> or
+      <link to="IGuestSession::directoryOpen"/> for instance).  Similarly,
+      there a methods for creating guest processes.
+
+      There can be up to 2048 objects (guest processes, files and directories)
+      a time per guest session.  Exceeding the limit will result in an error.
+<!-- @todo r=bird: Add specific VBOX_E_XXX error for this and document it here! -->
 
       When done with either of these objects, including the guest session itself,
       use the appropriate close() method to let the object do its cleanup work.
 
-      Every guest session has its own environment variable block which gets
-      automatically applied when starting a new guest process via
-      <link to="IGuestSession::processCreate"/> or <link to="IGuestSession::processCreateEx"/>.
-      To override (or unset) certain environment variables already set by the
-      guest session, one can specify a per-process environment block when using
-      one of the both above mentioned process creation calls.
+      Closing a session via <link to="IGuestSession::close" /> will try to close
+      all the mentioned objects above unless these objects are still used by
+      a client.
+
+      A set of environment variables changes is associated with each session
+      (<link to="IGuestSession::environmentChanges"/>).  These are applied to
+      the base environment of the impersonated guest user when creating a new
+      guest process.  For additional flexibility the <link to="IGuestSession::processCreate"/>
+      and <link to="IGuestSession::processCreateEx"/> methods allows you to
+      specify individual environment changes for each process you create.
+      With newer guest addition versions, the base environment is also made
+      available via <link to="IGuestSession::environmentBase"/>.  (One reason
+      for why we record changes to a base environment instead of working
+      directly on an environment block is that we need to be compatible
+      with older guest additions.  Another reason is that this way it is always
+      possible to undo all the changes you've scheduled.)
