Subject[PATCH net-next 3/4] net: dsa: mv88e6xxx: implement get_phy_address
Date
Avoid the need to specify a PHY for each physical port in the device tree
when phy_base_addr is not 0 (6250 and 6341 families).

This change should be backwards-compatible with existing device trees,
as it only adds sensible defaults where explicit definitions were
required before.
