Hi,

FYI, your patch has been queued to stable release 22.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/25. 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/3911c9348a430b3b94a0aa8a9f2392f0c58d1b2d

Thanks.

Luca Boccassi

Subject: [PATCH] net/mlx5: fix leak of flow indexed pools

[ upstream commit eefec46eeb89672815afd6c2497d21b928d77c54 ]

The cited commit allocated indexed pools but those pools
were never released. Fix it.

Fixes: b4edeaf3efd5 ("net/mlx5: replace flow list with indexed pool")
