I've also noticed that the number of hard_start_xmit failures in e1000
has increased significantly in version 5.1.13-k1. In version 5.0.43-k1 the
number of failures was much smaller.

With e100 and e1000, I see the very large numbers of the hard_start_xmit failure
when running very high packets-per-second rates (small packets).
I see virtually no failures with tulip. pktgen knows how to re-queue, but it's
curious it has to so often. For code that does not requeue, this could be even
more of a bummer.
