So, I think for my particular setup (that has no "real" PHY) we can have 
something like this in SW PoV:

stmmac -> xpcs -> SW-PHY / Fixed PHY

- stmmac + xpcs state would be handled by phylink (MAC side)
- SW-PHY / Fixed PHY state would be handled by phylink (PHY side)

This would need updates for Fixed PHY to support >1G speeds.
