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/8581b5dd0f3c4232a470667510e6d8a2cf417b0f

Thanks.

Luca Boccassi

Subject: [PATCH] net/i40e: fix error handling for QinQ filter

[ upstream commit 79ffb884262abe9caa297447b054b30057593969 ]

When installing a QinQ tunnel filter, errors were not properly caught
leading to the situation where the app got a successful return code even
though the filter was not properly installed. Add an appropriate log
message and error return code on error to fix.

Fixes: 116b7910d641 ("net/i40e: add QinQ filter create function")
