Hi,

FYI, your patch has been queued to stable release 22.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/09/24. 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://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/1822aa59aff6c2b7b3ad69cc50a543fe928a0ef4

Thanks.

Subject: [PATCH] net/hns3: remove QinQ insert support for VF

[ upstream commit f6e79b8d3968150736499bc225762b62fbf1b768 ]

In the HIP08 platform, the PF driver will notify VF driver to update
the PVID state [1], and VF will declare support QinQ insert when PVID
is disabled.

In the later platform (e.g. HIP09), the hardware has been improved,
so the PF driver will NOT notify VF driver to update the PVID state.

However, the later platform still have constraint: PVID and QinQ insert
cannot be enabled at the same time, otherwise, the hardware discards
packets and reports an error interrupt.

Plus, as far as we known, VF driver's users don't use the QinQ insert.

Therefore, we declare that the VF driver don't support QinQ insert.
