Of course the patch is completely ugly and violates any layering
principle one could think of. It was not submitted for inclusion :o)
Sure, but I think we should have a short-term workaround until
a better solution has been invented. Maybe dropping the packets
would be best for now, it only affects printks issued in paths
starting at qdisc_restart (-> hard_start_xmit -> ...). Queueing
the packets might also cause reordering since not all packets
are queued.
When I mentioned queueing, I was thinking of a netpoll-private queue
that would be hooked to a softirq or some such so that it would be
pushed out as soon as possible. Dropping may be the better approach 
I think so - just junk those packets.
