[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/05/25. 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/f96746df0877038b3473fbbb36721a7995c7629f

Subject: [PATCH] net/mlx5: fix Direct Verbs counter offset detection

[ upstream commit d953431da8e1ece042e33ba71650a3ba6b1e27c1 ]

This patch fixes a bug in
mlx5_flow_dv_discover_counter_offset_support()
uncovered by a warning reported by MSVC:

    ../drivers/net/mlx5/mlx5_flow_dv.c(19636): warning C5287:
        operands are different enum types 'ibv_flow_attr_type' and
        'ibv_flow_flags';
        use an explicit cast to silence this warning

IBV_FLOW_ATTR_FLAGS_EGRESS was incorrectly passed in to
type field of mlx5dv_flow_matcher_attr struct,
instead of flags field.
As a result counter offset support discovery returned a false positive
result on application with old rdma-core.

Bugzilla ID: 1758
Fixes: 4fd5e1484887 ("net/mlx5: fix counter offset detection")
