From 9ecf6ac17c321df396df283a771c29663e44871a Mon Sep 17 00:00:00 2001 From: Maor Gottlieb Date: Wed, 19 May 2021 11:47:27 +0300 Subject: RDMA/mlx5: Take qp type from mlx5_ib_qp Change all the places in the mlx5_ib driver to take the qp type from the mlx5_ib_qp struct, except the QP initialization flow. It will ensure that we check the right QP type also for vendor specific QPs.
