patch 'net/mlx5: remove unused reference counter' has been queued to stable release 21.11.1

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/14/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/c77572d2a1f816360cd92b6738821e81ec7c3d18

Thanks.

Kevin

Subject: [PATCH] net/mlx5: remove unused reference counter

[ upstream commit cff6aad7af61da8d31e146610f9b4a4875301ef4 ]

In the previous implementation, a count was used to record the number
of the references to a table resource, including the creation of the
table, the jumping to the table and the matchers created on the
table. Before releasing the table resource via the driver, it needed
to ensure that there is no reference to this table.

After the optimization of the resources management, the reference
count now is in the hash list entry as a unified solution for all the
resources management.

There is no need to keep the "refcnt" in the table resource
structure. It is removed in case that there is some unnecessary
memory overhead.

Fixes: afd7a62514ad ("net/mlx5: make flow table cache thread safe")
