Fixed-link make sense for a general purpose MAC which could be
connected to a PHY, or could also be used without a PHY. fixed-link
simplifies the code in that the MAC driver does not see a difference,
it all looks like a PHY.

However for a MAC which cannot be connected to a PHY, there is no need
to emulate a PHY. The MAC driver will be simpler. So i would not
recommend a fixed-link in this situation.
