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/90f0e78cdc9c1a6c838ff7a4c7f95856dfa20ec5

Thanks.

Luca Boccassi

Subject: [PATCH] app/testpmd: fix RSS hash key update

[ upstream commit 24e94a4c86c52f45a7a7c139e4e8484f3afe6d8f ]

There has logic problem in 'port_rss_hash_key_update()', the user input
will be overwritten by the call to 'rte_eth_dev_rss_hash_conf_get()',
so the RSS functions will not get update as expected.
