Hi,

FYI, your patch has been queued to stable release 24.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/13/26. 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/f50f90f6a0238957fbaa3b097ffdb70c107bd39a

Thanks.

Subject: [PATCH] net/mlx5: fix skipping PF representors

[ upstream commit 47e696635fa9ffc526c179946698d5cfd15113b7 ]

Offending patch changed logic of matching IB ports to requested
representors in mlx5 driver.
Each found IB port was matched against all requested representors.
Whenever:

- requested representor was VF or SF
- PF was not ignored
- IB port was physical port
- physical port index matched requested PF index

the physical port representor was probed.
If any of the above is false, mlx5 driver should have continue testing
other requested PF representors.
In the offending patch, the representor matching loop was stopped.
As a result, if mlx5 device with MPESW enabled was probed with the
following devargs:

	-a 08:00.0,dv_flow_en=2,representor=pf[0-1]vf[0,1]

Only 5 ports were probed (physical port 0 and all VF representors),
instead of 6 ports (physical port 1 is missing).

This patch fixes that by continuing representor matching loop
on physical port to PF index mismatch as described above.

Fixes: 2f7cdd821b1b ("net/mlx5: fix probing to allow BlueField Socket Direct")
