patch 'net/mlx5: fix SWS meter state initialization' has been queued to stable release 22.11.7

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 22.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/14/24. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/602cc6b95d5aa91bfc977f0fabbb81d9899f7361

Thanks.

Luca Boccassi

Subject: [PATCH] net/mlx5: fix SWS meter state initialization

[ upstream commit 0c37d8f7ba2cac289896de024d9c58a65ba3ece9 ]

Update the state initialization for SWS meter objects to properly
monitor ASO object availability. The PMD uses the meter 'state'
variable to track whether ASO objects are available for use.

This ensures that the SWS meter object state is correctly
initialized, allowing the PMD to accurately manage ASO resources
for metering functionality.

Fixes: 4359d9d1f76b ("net/mlx5: fix sync meter processing in HWS")
