[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/28/24. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/2a597e9f8b713ba95d47305d656f22533065c4a7

Subject: [PATCH] net/mlx5: fix hash Rx queue release in flow sample

[ upstream commit cf3f6ba146abe613c811a281ceadf7b22ef82ab6 ]

While the queue/RSS action was added to sample action lists,
the Rx hash queue resource was allocated in the sample action
translation to create the sample DR action later.

While there's a failure in the flow creation, the Rx hash queue
resource of the sample action list was destroyed in the wrong place.

This patch adds the checking to release the Rx hash queue
resource after the sample action release, to avoid one more
extra release if there's a failure.

Fixes: ca5eb60ecd5b ("net/mlx5: fix resource release for mirror flow")
