From: Honggang LI Subject: [PATCH 0/2] IB/core: Set invalid active widths to 1X when port is not active Date: Thu, 15 Mar 2018 17:02:12 +0800 Message-ID: <20180315090214.21706-1-honli@redhat.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: dledford@redhat.com, jgg@ziepe.ca, linux-rdma@vger.kernel.org Cc: noaos@mellanox.com, linux-kernel@vger.kernel.org, honli@redhat.com List-Id: linux-rdma@vger.kernel.org From: Honggang Li Before the mlx5 RoCE port negotiate the active rate and width with remote side, the mlx5_ib driver set them to zero. The tool 'ibstat' of 'infiniband-diags' package will panic as it read invalid width from the sys file. Set the active widths to lowest valid vaule as what ib_core module did for invalid rates.
