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. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
