patch 'net/mlx5: enhance error log for tunnel offloading' has been queued to stable release 21.11.5

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/25/23. 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://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/2681bfff6d10c06d0086b128872576266ea8f58f

Thanks.

Kevin

Subject: [PATCH] net/mlx5: enhance error log for tunnel offloading

[ upstream commit c9fecc1cc2886bcd626a656a5493841363dec6dd ]

Tunnel offloading is linked to running a port with the non-obvious
dv_xmeta_en=3 devargs. Hint at it for "normal" users.

Fixes: 4ec6360de37d ("net/mlx5: implement tunnel offload")
