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>

From: Honggang Li <honli@redhat.com>

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.

Honggang Li (2):
  IB/core: Set speed string to SDR for invalid active rates
  IB/core: Set width to 1X for invalid active widths when port is down
