This patch allows one to use the SO_BINDTODEVICE and a new ioctl against
net_device objects to send and receive regular routed traffic between two
interfaces on the same machine.  It also fixes a problem when using BINDTODEVICE:
the old code does not set the bound_if correctly when sending back the
syn-ack during TCP connection initialization.

I'm not sure how useful others will find it, but it amuses me ;)

Comments and suggestions welcome.

Thanks,
Ben
