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/f6aa87d8467f1bb7b079cd8d7c75722de305bd23

Thanks.

Luca Boccassi

Subject: [PATCH] net/bnxt: fix memory leak in VF VNIC query error path

[ upstream commit 374a9e57a59c847aede1d68474ac90787e3b2922 ]

bnxt_hwrm_func_vf_vnic_query_and_config() allocates vnic_ids before
calling bnxt_hwrm_func_vf_vnic_query(), but returns without freeing it
when that call fails.

Free vnic_ids on the error path too.

Fixes: 49947a13ba9e ("net/bnxt: support Tx loopback, set VF MAC and queues drop")
