patch 'net/mlx5: fix drop action release timing' has been queued to stable release 23.11.1

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/15/24. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=2864fd3102de0b12ee38816c850b320482ecfb92

Thanks.

Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 22a3761b782b7c46ca428209b15b4f7382a40a62 ]

When creating the drop action Devx object, the global counter set
is also used as in the regular or hairpin queue creation.

The drop action should be destroyed before the global counter set
release procedure. Or else, the counter set object is still
referenced and cannot be released successfully. This would cause
the counter set resources to be exhausted after starting and stopping
the ports repeatedly.

Fixes: 65b3cd0dc39b ("net/mlx5: create global drop action")
