I've finally gotten all of ebs's suggestions into the PHY code. Here

Some PHY are doing a better job with PHY specific registers I think ...
The gigabit for example isn't standard, and some PHYs sort-of manage to
deal with non-autoneg hubs in such a way that the "normal" aneg doesn't

been told a while ago, I have no direct experience here.
Ah, I should have been a little more clear. All the currently
implemented PHY drivers are just using the generic read_status
function. Different PHYs can assign their read_status function to be

your PHY isn't broken in some way (I've encountered a number that
you should be able to just use genphy.
Isn't the speed reporting of gigabit an implementation specific bit in
lots of PHYs ?
Well, it looks like there are some standard bits which say whether the
PHY supports gigabit. I used those.
