patch 'net/mlx5: fix bonding check' has been queued to stable release 25.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/23/26. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/538b08dda4b51b61128dd323b06a3ea2b83eac49

Thanks.

Kevin

Subject: [PATCH] net/mlx5: fix bonding check

[ upstream commit f6e478d5557a8d8c1407b35620fd7a32b8211a91 ]

mlx5 networking PMD supports probing ethdev ports based
on LAG configured on Linux kernel level.
In such cases, a single IB device is created in the kernel
and mlx5 PMD configured the device through this IB device.
In order to recognize whether PMD will run over LAG device or not,
mlx5 PMD relied on IB device name.

This patch fixes mlx5 networking PMD logic to rely on
mlx5_os_is_device_bond() introduced in previous commit,
instead of relying solely on IB device name.

Fixes: 2e569a370395 ("net/mlx5: add VF LAG mode bonding device recognition")
