Hi,

FYI, your patch has been queued to stable release 20.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/17/23. 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://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/9026ba04f9b356e04f970198e399c8eae8b53c2c

Thanks.

Luca Boccassi

Subject: [PATCH] net/hns3: allow adding queue buffer size hash rule

[ upstream commit 8095bf3e6d8ca7349e0a15f95407acd2063e7be0 ]

The maximum queue number from RSS flow rule allowed depends on
the maximum queue number (512) under one TC instead of the one
of Rx/Tx queue so as to eliminate restrictions on user usage.

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