Hi,

FYI, your patch has been queued to stable release 19.11.12

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/11/22. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/c367ca25baf377954e753ce2456764919460f2fe

Subject: [PATCH] net/hns3: fix RSS TC mode entry

[ upstream commit cdb9a7ae5f8f3b59b6de9dc2b52387636245e3a5 ]

The driver allocates queues only to valid TCs. But the driver also
configure queues for invalid TCs, which is unreasonable.

Fixes: c37ca66f2b27 ("net/hns3: support RSS")
