Maybe i've asked this before? What is on the other end of this link?
phy-mode internal and fixed link seems an odd combination. It might
just need some comments, if this is internally connected to a switch.

It is a bit odd mixing hex and decimal.

I _think_ the coding standard say the compatible should be first.

A phy should not have a phy-mode.
