Thanks for flagging Xueming.

The issue is that it was listed as fixing 059f18ae2aec ("net/iavf: add 
offload path for Tx AVX512") which goes back to 21.05.

This could have been avoided if the 'Fixes:' tag was correct, or if the 
authors replied to the email about queued backports :/

Requesting iavf/next-net-intel maintainers to check Fixes: tags are 
correct before merging.

DPDK 21.11.5 is already released with this patch. Any idea why it did 
not show up in validation for 21.11.5 ? Is it an issue for 21.11.5 ? How 
critical is it ?

I can revert it on the 21.11 branch, but it will need to wait until 
21.11.6 in December before it will be reverted in a released version.

thanks,
Kevin.
