patch 'net/mlx5/hws: fix flow rule hash capability' has been queued to stable release 23.11.6

[Shani Peretz]

Hi,

FYI, your patch has been queued to stable release 23.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/30/25. 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/shanipr/dpdk-stable

This queued commit can be viewed at:
https://github.com/shanipr/dpdk-stable/commit/36f622124829631ba7ccae17b4cf5d0083c6947b

Thanks.

Shani

Subject: [PATCH] net/mlx5/hws: fix flow rule hash capability

[ upstream commit 970309c7aa889ee06178c6476fe153e17096fc25 ]

Some cases are not supported for rule hash calculation. For example
when the matcher defined as FW matcher, or is the hash type is different
than CRC32. One case is when the distribute mode is not by hash, the
previous condition checked a wrong capability, while this commit fixes
it to the correct check.

Fixes: 7f5e6de53aae ("net/mlx5/hws: query flow rule hash")
