====================
net: dsa: realtek: rtl8365mb: improve handling of PHY modes

This series introduces some minor cleanup of the driver and improves the
handling of PHY interface modes to break the assumption that CPU ports
are always over an external interface, and the assumption that user
ports are always using an internal PHY.
