commit 6fa26208206c406fa529cd73f7ae6bf4181e270b upstream.
Report the correct speed in the port attributes when using a 56Gbps
ethernet link. Without this change the field is incorrectly set to 10.
Fixes: a9c766bb75ee ('IB/mlx4: Fix info returned when querying IBoE ports')
Fixes: 2e96691c31ec ('IB: Use central enum for speed instead of hard-coded
values')
