My understanding is that if the queue is not stopped, then you
should not get the hard xmit errors.  So, in a proper driver,
you should not see these printks.

By the way, is there any interest in adding my patch that also allows
pktgen to receive packets (and count the statistics, etc)?  I know
DaveM objected to the hook in the skb-receive logic some time back,
but maybe he has a different opinion now?
