Subject: [PATCH mlx5-next 13/13] net/mlx5: Move QP logic to mlx5_ib

From: Leon Romanovsky <[email-masked]>
Date: Mon, 13 Apr 2020 17:23:08 +0300

From: Leon Romanovsky <[email-masked]>

The mlx5_core doesn't need any functionality coded in qp.c, so move
that file to drivers/infiniband/ be under mlx5_ib responsibility.
