patch 'net/mlx5: enhance error log for tunnel offloading' has been queued to stable release 22.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/23. 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=9015baea292556c9e29c568470030297f7e67b94

Thanks.

Subject: [PATCH] net/mlx5: enhance error log for tunnel offloading
Cc: Xueming Li <xuemingl at nvidia.com>

[ 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")
