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

[Kevin Traynor]

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 03/06/22. 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/b362035a7e69c1e6cd65b4d94043a70cb2e2561e

Thanks.

Kevin

Subject: [PATCH] net/mlx5: remove unused function

[ upstream commit ad98ff6c500ad99a68b3e3f0a2cdabad5ee7d769 ]

The mlx5_l3t_prepare_entry() function is not used anymore.
This commit removes the unused mlx5_l3t_prepare_entry() function.

Fixes: 92ef4b8f1688 ("ethdev: remove deprecated shared counter attribute")
