Subject: [net 12/12] net/mlx5e: Block offload of outer header csum for GRE tunnel
From: Aya Levin <ayal@...dia.com>
The device is able to offload either the outer header csum or inner
header csum. The driver utilizes the inner csum offload. So, prohibit
setting of tx-gre-csum-segmentation and let it be: off[fixed].
Fixes: 2729984149e6 ("net/mlx5e: Support TSO and TX checksum offloads for GRE tunnels")
