Is there a reason this is used in the > example? Mac 1 connects to an xPON or xDSL subsystem depending on chip package. The phy-mode is not used by the driver and when the driver was written 6 months ago this was the best guess about the electrical protocol, left for documentation purposes. Your question made me re-investigate this, and I now note that both the xPON and xDSL "upper halves" as well as the switch on gmac0 are all on-die, so I think phy-mode = "internal" is more appropriate and I will re-send as such, and with some light documentation about what this ethernet connects to - since it's on the die so it'll always be the same.
