Subject: [PATCH mlx5-next 05/11] net/mlx5: Move SRQ functions to RDMA part
From: Leon Romanovsky <leonro@...lanox.com>
There is no need to keep SRQ which is RDMA object in mlx5_core.
In this patch, we partially move the execution code, while next patches
will move table initialization/release logic too.
