BTW, did you see any improvement when running pktgen from the host if no
regression was found? Since this can be reproduced with only 1 vcpu for
guest, may you try this bind? This might help simplify the problem.
vcpu0 -> cpu2
vhost -> cpu3
pktgen -> cpu1
Yes -- I ran the pktgen test from host to guest with the binding
described. I see an approx 5% increase in throughput from 4.12->4.13.
Some numbers:
host-4.12: 1384486.2pps 663.8MB/sec
host-4.13: 1434598.6pps 688.2MB/sec
That's great, at least we are aligned in this case.
Jason, any thoughts on this?

Good news is that pps is increased. I think the first step is moving
things a little bit ahead by reposting the optimization of tx polling.
I will post a new version soon.
Thanks
