Subject: [PATCH] mlx4: Fix IBoE reported rate
Date: Thu, 11 Nov 2010 18:09:45 +0200	[thread overview]
Message-ID: <20101111160945.GA29411@mtldesk30> (raw)

The link rate is the multiplication of the link speed in the link width. For
Etherent ports the rate is 10G so we use 4 for the witdh and 1 for speed so it
yields the correct rate.
