PATCH 1/1 mlx4: Fix IBoE reported rate
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.

Why not 1x and 10Gbps? We've been using that for a while.

I didn't think anyone cared about this. If there are no other objections I will send a new patch.
