Hi,

FYI, your patch has been queued to stable release 22.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/20/24. 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/f6a26c88648f181f03fc00b3731f8174d97dc222

Thanks.

Luca Boccassi

[ upstream commit c19580fb8e9ad6f153d46f731ec7cd2050b3021b ]

Use RTE_PTR_ADD where copying to the offset of a field in a structure
holding multiple fields, to avoid compiler warnings with decorated
rte_memcpy.

Fixes: 16a7dbc4f690 ("net/mlx5: make flow modify action list thread safe")
