Hi,

FYI, your patch has been queued to stable release 22.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/19/25. 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/30ea2c29d16d0858e3032746492974494400763a

Thanks.

Luca Boccassi

Subject: [PATCH] net/mlx5: adjust actions per rule limitation

[ upstream commit ab54e17fe2f5207d7b988d568344570e156551ad ]

HWS implementation added a limitation of 16 actions per rule,
which was incompatible with SWS limitation of 32 actions per rule.

Changing the hard coded limitation in PMD to 32.

Fixes: f13fab23922b ("net/mlx5: add flow jump action")
