Subject: [PATCH 1/2] IB/core: Set speed string to SDR for invalid active rates
Date: Thu, 15 Mar 2018 17:02:13 +0800 [thread overview]
Message-ID: <20180315090214.21706-2-honli@redhat.com> (raw)
In-Reply-To: <20180315090214.21706-1-honli@redhat.com>
From: Honggang Li <honli@redhat.com>
commit f1b65df5a232 ("IB/mlx5: Add support for active_width and
active_speed in RoCE"). Before this patch applied, the mlx5_ib
driver set default active_width and active_speed to IB_WIDTH_4X
and IB_SPEED_QDR.
Now, the active_width and active_speed are zeros if the RoCE port
is in DOWN state. The speed string should be set to " SDR" instead of
a blank string when active_speed is zero.
