I did, my main test system (BCM7445 w/ bcm_sf2) has one normal PHY driver and 3 fixed PHYs (including one for the CPU port/master netdev), see below. What kind of error do you get here? # ls -l /sys/class/net/gphy/phydev lrwxrwxrwx 1 root root 0 Jan 1 00:00 /sys/class/net/gphy/phydev -> ../../../f0b403c0.mdio/mdio_bus/f0b403c0.mdio/f0b403c0.mdio:05 # ls -l /sys/class/net/*/phydev lrwxrwxrwx 1 root root 0 Jan 1 00:01 /sys/class/net/eth0/phydev -> ../../../../Fixed MDIO bus.0/mdio_bus/fixed-0/fixed-0:00 lrwxrwxrwx 1 root root 0 Jan 1 00:00 /sys/class/net/gphy/phydev -> ../../../f0b403c0.mdio/mdio_bus/f0b403c0.mdio/f0b403c0.mdio:05 lrwxrwxrwx 1 root root 0 Jan 1 00:01 /sys/class/net/moca/phydev -> ../../../../../Fixed MDIO bus.0/mdio_bus/fixed-0/fixed-0:02 lrwxrwxrwx 1 root root 0 Jan 1 00:01 /sys/class/net/rgmii_1/phydev -> ../../../mdio_bus/sf2-1/sf2-1:00 lrwxrwxrwx 1 root root 0 Jan 1 00:01 /sys/class/net/rgmii_2/phydev -> ../../../../../Fixed MDIO bus.0/mdio_bus/fixed-0/fixed-0:01 # ls -l /sys/class/mdio_bus/fixed-0/*/attached_dev lrwxrwxrwx 1 root root 0 Jan 1 00:01 /sys/class/mdio_bus/fixed-0/fixed-0:00/attached_dev -> ../../../../rdb/f04a0000.ethernet/net/eth0 lrwxrwxrwx 1 root root 0 Jan 1 00:02 /sys/class/mdio_bus/fixed-0/fixed-0:01/attached_dev -> ../../../../rdb/rdb:switch_top@f0b00000/f0b00000.ethernet_switch/net/rgmii_2 lrwxrwxrwx 1 root root 0 Jan 1 00:02 /sys/class/mdio_bus/fixed-0/fixed-0:02/attached_dev -> ../../../../rdb/rdb:switch_top@f0b00000/f0b00000.ethernet_switch/net/moca # ls -l /sys/class/mdio_bus/f0b403c0.mdio/f0b403c0.mdio\:05/attached_dev lrwxrwxrwx 1 root root 0 Jan 1 00:02 /sys/class/mdio_bus/f0b403c0.mdio/f0b403c0.mdio:05/attached_dev -> ../../../../f0b00000.ethernet_switch/net/gphy > > - Woojung > -- Florian
