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 03/21/25. 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/723d4e015b1938b51e748cf63ccefd27f92db60e

Thanks.

Luca Boccassi

Subject: [PATCH] net/mlx5/hws: fix GTP flags matching

[ upstream commit a31da10717be6a79877621e94eeb003f547c5f88 ]

Support GTP flags in non-template on top of HWS.
Currently, only extension flag was supported,
Added support to all bits under v_pt_rsv_flags.

Fixes: c55c2bf35333 ("net/mlx5/hws: add definer layer")
