patch 'net/iavf: fix secondary process Rx path selection' has been queued to stable release 25.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/23/26. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/29100027f254baf8a646a6db90a693417eee9313

Thanks.

Kevin

Subject: [PATCH] net/iavf: fix secondary process Rx path selection

[ upstream commit 7d0126bc830280a0e73c7c9429177e5d0d9090bf ]

Commit 3f59c3d97a89 ("net/iavf: use same Rx path across processes")
changed the way that secondary processes selected their Rx burst
function. Instead of letting secondary processes select their own
function, they now used the function selected by the primary process.
However, the primary process only selects the function at device start,
so if the primary process hadn't started the device by the time the
secondary process was selecting its Rx burst function, the secondary
process would not select the correct function.

This commit addresses this issue by allowing the secondary process to
select the path if the device has not been started yet.

Fixes: 3f59c3d97a89 ("net/iavf: use same Rx path across processes")
