patch 'net/mlx5: fix HWS registers initialization' has been queued to stable release 23.11.1

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/15/24. 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=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=ca1084cd4891d179c6a2a8e595358a9045fd3c9b

Thanks.

Subject: [PATCH] net/mlx5: fix HWS registers initialization
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 1beeb6d71fcc2fa73d149071c6880573d78fa071 ]

The method to initialize tag registers by using capability bits is
not supported on some old NICs. In the meanwhile, the HWS for flow
rule insertion is not supported either. There is no need to
initialize HWS only resource on the old NICs.

Fixes: 48041ccbaa8d ("net/mlx5: initialize HWS flow registers in shared context")
