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/d1d03a88ecfe7e3b069f1bfdf477a04c97972b9b

Thanks.

Luca Boccassi

Subject: [PATCH] net/gve: fix RSS config memory leak on close

[ upstream commit 233728918e91fd7ca40272495866dcbb975b3bd1 ]

Free rss_config resources during device close to avoid leaking
redirection table and hash key memory. Also, memset the entire
gve_rss_config struct to 0 to avoid leaking RSS hash function or hash
types.

Fixes: 63ef54569760 ("net/gve: support RSS configuration update")
