[ Upstream commit 95aac2cdafd8c8298c9b2589c52f44db0d824e0e ]
Functions __set_port_type and mlx4_check_port_params returned -EINVAL while the proper return code is -EOPNOTSUPP as a result of an unsupported operation. All drivers should generate this and all users should check for it when detecting an unsupported functionality.
