22.11.4 iavf issue

22.11.4 iavf issue

[Kevin Traynor]

Hi Xueming,

Can I request that you hold off releasing DPDK 22.11.4 for a few days,
so we can come to a conclusion about:
https://bugs.dpdk.org/show_bug.cgi?id=1337

It means that OVS deadlocks under certain circumstances with iavf
driver. I recently moved some of the supported OVS branches to using
DPDK 22.11.3, so ideally, 22.11.4 would have a fix for this and we can
just move again.

I have already reverted the backport [0] that triggered this issue for
DPDK 21.11.6.

thanks,
Kevin.
