patch 'net/iavf: fix VLAN insertion in vector path' has been queued to stable release 22.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/11/23. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=5c23daed42046e8ef4e82cdb6c134c6ff817fe80

Thanks.

Subject: [PATCH] net/iavf: fix VLAN insertion in vector path
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit efe1b63775e8369b867f411d7bf8f61e97bd446b ]

As the VLAN insertion is partially supported in vector path,
the behavior is different in scalar and vector path.
For a VLAN packet, if using scalar path, the new VLAN tag will
be inserted after the original VLAN tag. If using vector path,
the new VLAN tag is inserted before the original VLAN tag.
To avoid any misleading, disable VLAN insertion in vector path.

Fixes: 059f18ae2aec ("net/iavf: add offload path for Tx AVX512")
