patch 'net/mlx5/hws: fix matcher reconnect' has been queued to stable release 23.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/14/24. 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=82315fbf7fdf3b733c1a7d0df5368664e237ae4f

Thanks.

Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit f21215b733abb2c80f1b58750d74de27f9233d62 ]

If error happens during disconnect of the first matcher in the
list, the matcher should be reconnected back as the first matcher.

Fixes: b81f95ca770d ("net/mlx5/hws: support default miss table")
