This includes ability to ignore overrun for CQ which intended for cross-channel, export device capability and configure the QP to be sync master/slave queues. The cross-channel enabled QP supports combination of three possible properties: * WQE processing on the receive queue of this QP * WQE processing on the send queue of this QP * WQE are supported on the send queue Reviewed-by: Sagi Grimberg Signed-off-by: Leon Romanovsky Signed-off-by: Doug Ledford --- include/linux/mlx5/qp.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'include/linux') diff --git a/include/linux/mlx5/qp.h b/include/linux/mlx5/qp.h index a9ad40169191..fd1ff4110e80 100644 --- a/include/linux/mlx5/qp.h +++ b/include/linux/mlx5/qp.h @@ -130,6 +130,9 @@ enum { MLX5_QP_BIT_RWE = 1 << 14, MLX5_QP_BIT_RAE = 1 << 13, MLX5_QP_BIT_RIC = 1 << 4, + MLX5_QP_BIT_CC_SLAVE_RECV = 1 << 2, + MLX5_QP_BIT_CC_SLAVE_SEND = 1 << 1, + MLX5_QP_BIT_CC_MASTER = 1 << 0 }; enum { -- cgit v1.2.3
