patch 'net/iavf: fix VLAN strip setting after enabling filter' has been queued to stable release 23.11.5

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/10/25. 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=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=f2c11a141c46c6a9d461493b70490940d8147680

Thanks.

Subject: [PATCH] net/iavf: fix VLAN strip setting after enabling filter
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 3bfad066f9b4764981c9ad90a750fa6f1afcf15a ]

For i40e kernel drivers which support either vlan(v1) or vlan(v2)
VIRTCHNL OP, it will set strip on when setting filter on.
But DPDK side will not change strip flag.
To be consistent with DPDL side, explicitly disable strip again.

Bugzilla ID: 1725
Fixes: e25c7ed114b2 ("net/iavf: fix VLAN offload strip flag")
