Neither does any other PHY driver. It should be possible to tell if a
PHY supports 1G by looking at register values. If this does not work
for fixed_link, it means we are missing something in the emulation.
That is what we should be fixing.

Also, this change has nothing to do the lp_advertise, what you
previously said the problem was. At the moment, i don't get the
feeling you have really dug all the way down and really understand the
root causes.
