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 07/15/26. 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/73fe1cb56d2ecbaf3edc6da680ee350940c11062

Thanks.

Luca Boccassi

Subject: [PATCH] net/iavf: fix leak of flex metadata extraction field

[ upstream commit 94f6e8f48462c24bb401fd93689a1f4574ab3ecc ]

Function iavf_init_proto_xtr() allocates vf->proto_xtr as part of the
device init sequence, but no shutdown function frees this memory again.
Add appropriate free calls to fix this memory leak.

Fixes: 12b435bf8f2f ("net/iavf: support flex desc metadata extraction")
