patch 'net/intel: update key length when getting RSS key' has been queued to stable release 25.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/02/26. 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/5e25ee3c59bf8a8d6a684200a33a1d84f9fe3698

Thanks.

Kevin

Subject: [PATCH] net/intel: update key length when getting RSS key

[ upstream commit 23e5d5ed70c89715d1a29ee780ade74c8aab1998 ]

When adding the i40e PMD, the rss_hash_conf_get function was changed
to update the RSS key len.
The corresponding functions for ixgbe & e1000 were not updated to
follow the new convention.

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