IB/mlx5: Add create and destroy functionality for Raw Packet QP

Browse source

This patch adds support for Raw Packet QP for the mlx5 device.

Raw Packet QP, unlike other QP types, has no matching mlx5_core_qp
object but rather it is built of RQ/SQ/TIR/TIS/TD mlx5_core object.

Since the SQ and RQ work-queue (WQ) buffers are not contiguous like
other QPs, we allocate separate buffers in the user-space and pass
the address of each one of them separately to the kernel.
