Hi,

FYI, your patch has been queued to stable release 22.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/25. 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/e9063c8f242260215659a8719d14f1a0f17311a1

Thanks.

Luca Boccassi

Subject: [PATCH] net/hns3: fix resources release on reset

[ upstream commit 361eab82df67c09cb84a9e2e66c0d93a84be610d ]

Some resources, like, unmapping Rx interrupt, doesn't perform
when execute dev_stop on reset. This will lead to other issues.

Fixes: 2790c6464725 ("net/hns3: support device reset")
