[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 03/02/26. 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/7d18a29835ae6a74615b3855e55c84ea450e3179

Thanks.

Kevin

Subject: [PATCH] common/cnxk: fix engine capabilities fetch logic

[ upstream commit aa656824205dac6b55dfde7551cb8f50a5d98569 ]

For CN9k platform, incorrect status is checked from LOAD
FVC instruction while retrieving engine capabilities.

The loop is updated for a valid return status check on
LOADFVC instruction.

Fixes: 7c67c489d466 ("common/cnxk: fetch engine capabilities")
