Hi,

FYI, your patch has been queued to stable release 24.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/26. 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/67e73c9b7ac51ee26896048089660a9f61dc54d6

Thanks.

Luca Boccassi

Subject: [PATCH] net/bnxt: fix MPC channel disable mask

[ upstream commit 5f3d65d6f39652809d810c059c426aeaa5265c0a ]

The MPC channel enable bitmap is cleared before it is used to build
the channel mask. As a result, no channels are selected for disable.

Preserve the bitmap before clearing it and use the saved value when
building the channel mask.

Found by InfoTeCS on behalf of Linux Verification Center
(linuxtesting.org) with SVACE.

Fixes: 80317ff6adfd ("net/bnxt/tf_core: support Thor2")
