    Subject[PATCH 5.12 039/178] net/mlx5e: Block offload of outer header csum for GRE tunnel
    Date
    From: Aya Levin <ayal@nvidia.com>

    [ Upstream commit 54e1217b90486c94b26f24dcee1ee5ef5372f832 ]

    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")
