Re: 2.6.11-rc5 and 2.6.12: cannot transmit anything

[David S. Miller]

Probably your link is never coming up.  We won't send packets
over the wire unless the device is in the link-up state.

However, if ->dequeue() is returning NULL, there really aren't
any packets in the device queue to be sent.

If you want, add more tracing to pfifo_fast_dequeue() since
that's almost certainly which queueing discipline is hooked
up to your VIA Rhine device as it's the default.
