The SCTP tunnel packet of iavf cannot be forwarded in avx512 mode Need to clarify this sentence. It looks like it is not a functional bug where avx512 mode is selected and then an SCTP tunnel packet cannot be sent. Instead, it is a possible performance issue that avx512 mode will not be selected where it might have been due to unneeded additions (RTE_ETH_TX_OFFLOAD_*_TNL_TSO) to IAVF_TX_NO_VECTOR_FLAGS. @IAVF maintainers - please confirm my analysis is correct ? In that case, as it is a possible performance issue in a specific case for a single driver I think it is non-critical for 21.11 and we can just revert the patch on the branch and wait for 21.11.6 release in December. thanks, Kevin. >> commit 9b7215f150d0bfc5cb00fce68ff08e5217c7f2b3 on v22.11.3-rc1. >> This commit is for the new feature (avx512 checksum offload) in DPDK 23.03, which should not be backported to the LTS version since avx512 checksum offload is not supported in v22.11.3 LTS. >> > > 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.
