Hi,

FYI, your patch has been queued to stable release 24.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/13/26. 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/b5550ec4c0c5dcfdb1559c700642cd6b4767d138

Thanks.

Luca Boccassi

Subject: [PATCH] net/bnxt: fix RSS hash mode configuration for VF

[ upstream commit 3fd58de5a903e62ec0ba492f6c1b0c6c55db2c98 ]

Fixed VFs attempting global RSS configuration which is not
permitted by firmware. VFs (including trusted VFs) must use
per-VNIC RSS configuration with actual vnic_id and rss_ctx_idx
values.

Fixes: 8b9adaf0da6b ("net/bnxt: support RSS on ESP and AH headers")
