[PATCH rdma-next v1 4/9] RDMA/mlx5: Use direct modify QP implementation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Leon Romanovsky <leonro@xxxxxxxxxxxx>

As a preparation to removal hand crafted mlx5_qp_context, convert
counter code to use mlx5_cmd_exec_in() directly.
