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 11/07/26. 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/a19786538658385fa07820001bf9c635be6760ec

Thanks.

Luca Boccassi

Subject: [PATCH] net/iavf: fix false success on flow validation

[ upstream commit fae5ce5de601e286ca009f4a3d914d5824df0337 ]

`iavf_parse_engine_validate()` sets an error when validation fails, but
then returns the engine pointer. `iavf_flow_process_filter()` treats a
non-NULL engine as success, so `rte_flow_validate()` can accept an
invalid flow.

Return `NULL` on validation failure and return the engine only after
validation succeeds.

Fixes: ff2d0c345c3b ("net/iavf: support generic flow API")
