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/38eb97771c115373ff9aa4a99e53679aad9674bd

Thanks.

Luca Boccassi

Subject: [PATCH] net/hns3: fix interrupt rollback

[ upstream commit 9e911049ac5188be7e080aa8699c0d8e97b32110 ]

When the port is started, if the Tx queue fails to be started,
the map interrupt should be rolled back.

Fixes: fdfde7a4a0f8 ("net/hns3: fix mbuf leakage")
