patch 'app/testpmd: include IP fields in UDP RSS option' has been queued to stable release 25.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/01/26. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/236fe24e637c1b1c55ffee48a28014304ba087fb

Thanks.

Kevin

Subject: [PATCH] app/testpmd: include IP fields in UDP RSS option

[ upstream commit 4984ad2f6e60a3f1126a1ca7b9bf8f5bd9aea276 ]

The --rss-udp option is documented as enabling IPv4/IPv6 + UDP RSS, but it
currently sets the RSS hash functions to RTE_ETH_RSS_UDP only.

On PMDs that translate this directly to L4 port extracts, this can build a
L4-only RSS key. Add RTE_ETH_RSS_IP when --rss-udp is selected so the
configured key matches the documented IPv4/IPv6 + UDP behavior.

Make --rss-ip additive as well, so combining --rss-ip and --rss-udp is
order-independent.

Fixes: 8a387fa85f02 ("ethdev: more RSS flags")
