[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 24.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/22/26. 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/e15ef7dd9e31f3d69e271b6e40511f5bc7d893a9

Thanks.

Luca Boccassi

Subject: [PATCH] net/mlx5: fix port down in link detection failure

[ upstream commit 85182f9006c3f26ba6c61148110565ae3e655573 ]

The port down state was not initialized in the error branch of link
detection when MLX NIC link status update failed (ret < 0).
This resulted in incorrect link state reporting, as the device
retained stale link status instead of reflecting the actual down
state under error conditions.

Fixes: 1256805dd54d ("net/mlx5: move Linux-specific functions")
