    Subject[PATCH AUTOSEL 5.4 061/266] IB/mlx5: Fix DEVX support for MLX5_CMD_OP_INIT2INIT_QP command
    Date
    From: Mark Zhang <markz@mellanox.com>

    [ Upstream commit d246a3061528be6d852156d25c02ea69d6db7e65 ]

    The commit citied in the Fixes line wasn't complete and solved
    only part of the problems. Update the mlx5_ib to properly support
    MLX5_CMD_OP_INIT2INIT_QP command in the DEVX, that is required when
    modify the QP tx_port_affinity.

    Fixes: 819f7427bafd ("RDMA/mlx5: Add init2init as a modify command")
