Hi,
FYI, your patch has been queued to stable release 24.11.3
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/23/25. 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/kevintraynor/dpdk-stable
This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/026a4bd924acb30ec7ed294ae78b63209903dcbc
Thanks.

Subject: [PATCH] net/i40e: fix RSS on plain IPv4
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
[ upstream commit 5d47e73e5f4f2eb69bd73f642cfd72b49436bf96 ]
Currently, i40e driver is missing the flag reporting RSS support for
plain IPv4. Configuring rss function to RTE_ETH_RSS_IPV4 returns an
error: "invalid rss hash function value", even though the HW supports
RSS on plain IPv4 traffic.
Fixes: a286ebeb0714 ("net/i40e: add dynamic mapping of SW flow types to HW pctypes")
