Hi,

FYI, your patch has been queued to stable release 22.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/25. 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/4eea4fd0291f90f85ae65130bc5d399a2e099d08

Subject: [PATCH] net/enetfec: reject Tx deferred queue

[ upstream commit dd6b3572a310d0f3e045d8e9d1eb5f6181729d08 ]

This patch adds a check to reject configuration of Tx deferred start,
which is not supported by the enetfec PMD. This ensures that unsupported
features are explicitly handled and reported.

Fixes: bb5b5bf1e5c6 ("net/enetfec: support queue configuration")
