One of the reasons drivers don't do this consistently his that historically, hardware has not consistently supported link state detection. This now does seem to be a standard feature, but I think it would be useful to continue to support some notion of a driver not supporting it, hence my thoughts on a link state capability: only test link state if the driver can implement it. Otherwise, you end up with a link state undefined state, which likely comes to much the same thing, and is presumably what in practice you get today on drivers that don't set it.
