Hi,

FYI, your patch has been queued to stable release 22.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/25. 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/12296df8a2395117d1027c9883691a9ad167fb5a

Thanks.

Luca Boccassi

Subject: [PATCH] net/cnxk: fix descriptor count update on reconfig

[ upstream commit ad23295cb8217390b9f966ad5ee10a4e21f9c20b ]

In Rx queue setup, input descriptors count is updated as per
requirement, and stored. But during port reconfig , this
descriptor count will change again in rx queue setup.
Hence, will need to store the initial input descriptor count.

Fixes: a86144cd9ded ("net/cnxk: add Rx queue setup and release")
