patch 'net/enetfec: reject multi-queue configuration' has been queued to stable release 24.11.4

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/05/25. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/0c60dea6e6b1ade68d942b249e460889cda0b85a

Thanks.

Kevin

Subject: [PATCH] net/enetfec: reject multi-queue configuration

[ upstream commit b1c162858c1efc31c8b4ac26b5943b7b8dd65bf8 ]

The enetfec PMD currently supports only a single TX queue. This patch
adds a check to prevent users from configuring more than one queue,
ensuring predictable behavior and avoiding unsupported configurations.

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