Merge branch 'mlx5_tx_steering' into rdma.git for-next
Leon Romanovsky says: ==================== Those two patches from Michael extends mlx5_core and mlx5_ib flow steering to support RDMA TX in similar way to already supported RDMA RX. ==================== Based on the mlx5-next branch at git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux Due to dependencies * branch 'mlx5_tx_steering': RDMA/mlx5: Add support for RDMA TX flow table net/mlx5: Add support for RDMA TX steering
