Just to sync, I just sent kernel patches which should eliminate the case 
when EINVAL is seen by rate_show after calling into the mlx4 driver.  
This addresses point #2, as for #3, I made a check and forced Ethernet 
link layer on IB port, in this case the mlx4 driver issues the ethernet 
port query command and it returns valid value for active_speed (4) so I 
didn't patch that code too. As for libibumad fixes, I'm not dealing with 
that...
