Are you referring to the fact that after setting the enabled speed, the IB spec does not mandate a link renegotiation and hence one may not have occurred so the enabled speed can be out of whack with the active speed ? Also, isn't there a similar issue with extended speeds (and force_link_speed_ext) ? If so, should that also be part of this patch ? Same issue also is there for link width as it works the same way as link speed. Maybe that too is yet another patch.
