Subject: net/mlx5e: Block offload of outer header csum for UDP tunnels
Patch-mainline: v5.13-rc7
Git-commit: 6d6727dddc7f93fcc155cb8d0c49c29ae0e71122
References: git-fixes

The device is able to offload either the outer header csum or inner
header csum. The driver utilizes the inner csum offload. Hence, block
setting of tx-udp_tnl-csum-segmentation and set it to off[fixed].

Fixes: b49663c8fb49 ("net/mlx5e: Add support for UDP tunnel segmentation with outer checksum offload")
