Hi Tommy:
What if we take a more direct approach and just drop the packets before
it hits hard_start_xmit? This also makes it easy for the drivers to do
TX ring flushing if it's necessary since we're guaranteeing (for drivers
that are not lockless anyway) that once carrier goes off while the xmit
lock is held hard_start_xmit will not be called again.
Cheers,
