Besides our Kirkwood Reference design, there is another group of board on which the eth interface is not connected to a phy but to a swtich for some board internal communication. The configuration of the switch is handled by an EEPROM or by the bootloader, but on the kirkwood side, the port is always configured as 1000 Mbits, full duplex.
