Subject: [PATCH v2] mlx4: Fix IBoE reported rate
Date: Mon, 15 Nov 2010 16:04:39 +0200	[thread overview]
Message-ID: <20101115140439.GA20131@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 1 for the witdh and 4 for speed so it
yields the correct rate.

Signed-off-by: Eli Cohen <eli-VPRAkNaXOzVS1MOuV/RT9w@public.gmane.org>
---
Changes: Use 1X for width and 4 for speed.
It should be noted that in the future (for other devices),
active_width and active_speed may have other values to relflect the
correct rate.
