Log:
net: Add alx driver for Atheros AR8161 and AR8162 (Closes: #699129)
Mark as staging, since it has not been accepted upstream.
Define some trivial networking features to support it.

+Subject: net: add new QCA alx ethernet driver which supercedes atl1c
+Bug-Debian: http://bugs.debian.org/699129
+Forwarded: no
+
+This driver is intended to replace the atl1c driver and provide
+support for a two new chipsets. Qualcomm Atheros (QCA) is commiting
+to fixing all bugs found on this driver. Test results show this
+driver performs better than atl1c on all supported chipsets, closes
+the gap between TX and RX throughput (they now match) and has also
+been verified with ASPM enabled on all supported chipsets. This
+driver and patch also have addressed all sparse and checkpatch
+warnings.
+
+QCA is commiting on fixing all bugs upstream on this driver.
+This driver is also permissively licensed thereby enabling
+developers of other OSes to cherry pick this driver to port to
+their OS, such as FreeBSD.
+
+Both atl1c and alx driver support the following chipsets:
+
+1969:1063 - AR8131 Gigabit Ethernet
+1969:1062 - AR8132 Fast Ethernet (10/100 Mbit/s)
+1969:2062 - AR8152 v2.0 Fast Ethernet
+1969:2060 - AR8152 v1.1 Fast Ethernet
+1969:1073 - AR8151 v1.0 Gigabit Ethernet
+1969:1083 - AR8151 v2.0 Gigabit Ethernet
+
+But alx also supports these two new chipstes:
+
+1969:1091 - AR8161 Gigabit Ethernet
+1969:1090 - AR8162 Fast Ethernet
+
+We leave the atl1c driver in place for now but mark it as
+deprecated in favor for the alx. Linux distributions should
+consider using alx moving forward and any issues found with
+the alx driver will be proactively addressed and tracked by
+assigned by QCA engineers.
+
+For more detail including a shiny graph of throughput in comparison
+to atl1c see the new shiny alx driver home page:
