Hi,

FYI, your patch has been queued to stable release 24.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/22/26. 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/a1cdd5f6562e2c0b32b37171550d7b045b020421

Thanks.

Luca Boccassi

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")
