Hello Sunil, Marko and Ian.
Mike worked to identify the reason for the performance issue
reported by you a while ago. He summarized below. I wonder
if you can give a try on his patch too and tell us if we are
on the right track.
Thanks,
fbl

Hello Flavio,
Great patch, I think you really did a lot to improve the code here and
I think that's borne out by the consistent performance improvements
across multiple tests.
Regarding the 4% regression that Intel detected, I found the following
white paper to describe the "scatter" test:

VSPERF phy2phy_tput uses 2 dpdk pmds and performs zero packet loss
test(RFC2544) with bidirectional traffic.

This patch split out the common code between vhost and
dpdk transmit paths to shared functions to simplify the
code and fix an issue.
The issue is that the packet coming from non-DPDK device
and egressing on a DPDK device currently skips the hwol
preparation.
This also have the side effect of
