Hi,
FYI, your patch has been queued to stable release 24.11.2
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/28/25. 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/kevintraynor/dpdk-stable
This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/535cab510acc023f6a9bee4214396f0ac444987c
Thanks.

Subject: [PATCH] net/mlx5: fix non-template flow validation on create
[ upstream commit f8ce702cd05f555ab8a52e6d827f096d80fbb825 ]
Currently, a non template rule on top of HWS can
be created successfully although validation fails.
Added in flow creation, the rule validation,
And deduce the items flags from the validation items loop.
Fixes: 0989f6808401 ("net/mlx5: update NTA rule pattern and actions flags")
