Subject: [PATCH rdma-next 00/18] Refactor mlx5_ib_create_qp (Part I)

From: Leon Romanovsky <leonro@...lanox.com>

Hi,

This is first part of series which tries to return some sanity
to mlx5_ib_create_qp() function. Such refactoring is required
to make extension of that function with less worries of breaking
driver.

Extra goal of such refactoring is to ensure that QP is allocated
at the beginning of function and released at the end. It will allow
us to move QP allocation to be under IB/core responsibility.

It is based on previously sent [1] "[PATCH mlx5-next 00/24] Mass
conversion to light mlx5 command interface"

Thanks
