patch 'net/mlx5/hws: fix field copy bind' has been queued to stable release 22.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/15/23. 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=461a81717f5d82967baf371f6d1c8be06480a405

Thanks.

Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 1e6cb8f290b65d27c94e0caf108d6c35c30fe42b ]

Fix an issue with binding for unused DW selectors,
these selectors are set to zero but zero is also
a valid value used for DMAC_47_16.

Fixes: c55c2bf35333 ("net/mlx5/hws: add definer layer")
