patch 'app/testpmd: fix RSS hash key update' has been queued to stable release 23.11.5

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/28/25. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=31817dc08ead234519e36e00a40e968c2669d499

Subject: [PATCH] app/testpmd: fix RSS hash key update
Cc: Xueming Li <xuemingl at nvidia.com>

[ 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.
