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 03/21/26. 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/9278ffe95ddcab4dc9a23c2e0df01e25b9a87a33

Thanks.

Luca Boccassi

Subject: [PATCH] net/bnxt: fix uninitialized read

[ upstream commit aff31f4ea10a1653731439ba20a79bb9d6c3844d ]

batch_info->enabled is read in tfc_mpc_batch_start() before it is
initialized.

Initialize batch_info to avoid this.

Fixes: 67ad40007cd6 ("net/bnxt/tf_ulp: fix VFR cleanup and stats lockup")
