[Babel-users] Bug in ahcpd: tunnel interfaces not handled correctly

[Juliusz Chroboczek]

There's a bug in ahcpd -- it won't work correctly if the first
interface you pass on the command-line doesn't have a MAC-48 address,
e.g. if it's a tunnel.  An IPv6 address will be autogenerated, but it
won't be removed when you kill ahcpd.

As a workaround, make sure that the first interface you pass to ahcpd
is a hardware interface, e.g.

  ahcpd wl0 tun0

or remove the address manually after killing ahcpd.
