No such thing in reality. The kernel has an obsolete idea of a fixed PHY
which is a software-emulated PHY to represent a fixed link, but that is
basically dead with phylink (there is now no PHY for fixed links under
phylink).
As I stated, "phy-mode" describes how the MAC needs to configure its
PHY facing interface, whether there is or is not a PHY present. One can
argue that it's misnamed, but it's buried in deep DT history going back
decades, and there's a rule that we don't break backwards compatibility.
