If cmode of the port is set to 2500base-x, though, the PHY still reports 1000 Mbps (the PHY register itself does not differentiate between 1000 Mbps and 2500 Mbps - it thinks it is running at 1000 Mbps, although clock is 2.5x faster). Look at the cmode and set SPEED_2500 if cmode is set to 2500base-x. Also tell mv88e6xxx_port_setup_mac the PHY interface mode corresponding to current cmode in terms of phy_interface_t.
