Subject: patch 'net/mlx5: fix probing with secondary bonding member' has been queued to stable release 21.11.2
Date: Tue, 10 May 2022 13:29:50 +0100
Message-ID: <20220510123010.159523-13-ktraynor@redhat.com> (raw)
In-Reply-To: <20220510123010.159523-1-ktraynor@redhat.com>

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/15/22. 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/99ba358268c8bd8d1bb387ea842a88ca45ffdbe1

Thanks.

Kevin

Subject: [PATCH] net/mlx5: fix probing with secondary bonding member

[ upstream commit f956d3d4c33cdfac5e352f457050029bd5c9b8a8 ]

Users can probe primary or secondary PCIe id when bonding is
configured.
1. -a 0a:00.0,representor=pf[0-1]vf[0-1], PMD probes 5 ports
totally: bonding device plus 4 representor ports.
2. -a 0a:00.1,representor=pf[0-1]vf[0-1], PMD only probes 2
representor ports.

Under the 2nd condition, bonding IB device doesn't have the same
PCIe id and PMD needs to check bonding relationship otherwise
probe failure.

Fixes: 6856efa54eea ("net/mlx5: fix PF leak on PCI probing failure")
