Hi,
FYI, your patch has been queued to stable release 22.11.3
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/11/23. 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=22.11-staging
This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=9b95d1a0f8d7dbb03fdaa27f2bb1ccc5c10a8f3a
Thanks.

Subject: [PATCH] net/ice: fix RSS hash key generation
Cc: Xueming Li <xuemingl at nvidia.com>
[ upstream commit b9f28be1bf72e120041416b461325941fd97cac0 ]
Current code just generated 40 bytes standard rss
hash key of ice driver. The extended 12 bytes
were filled by hardware and were invalid for users.
This patch generate 52 bytes rss hash key for ice
driver just as other drivers.
Fixes: 50370662b727 ("net/ice: support device and queue ops")
Fixes: 20d6a017e148 ("net/ice: fix build with GCC 12")
