[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/28/23. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/2b15b1cd4a3994d5a09aa31990d7075d4caf9057

Subject: [PATCH] net/bnxt: fix RSS hash in mbuf

[ upstream commit 031102f531e87e25174d4744c4ced92e5b291891 ]

By clearing mbuf->hash.fdir.id in the data path, the driver is
corrupting the RSS hash value populated in the mbuf as they
are defined as a union.

This patch fixes the problem by removing the code that clears
mbuf->hash.fdir.id.

Fixes: 17b6c8386d73 ("net/bnxt: fix mark handling")
