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/c4022078a3680d10e56194dbbcf5e1cfc1d6b2f5

Thanks.

Luca Boccassi

Subject: [PATCH] net/ixgbe: fix missing HW write in IPsec

[ upstream commit 7b1f45c4b282219ba07e8d8012723239abf6984b ]

When removing an SA and finding ourselves with zero refcount on an IP
table entry, we zero out the IP table registers, but do not write them.
Add the missing write.

Fixes: 9a0752f498d2 ("net/ixgbe: enable inline IPsec")
