++
++Ethtool readme for selecting different PHY address.
++
++Before doing any ethtool command you should make sure the current PHY
++address is expected. The default PHY address is 1(port 1).
++
++You can change current PHY address to X(0~4) by doing follow command:
++# echo X > /proc/rt2880/gmac
++
++Ethtool command also would show the current PHY address as following.
++
++# ethtool eth2
++Settings for eth2:
++ Supported ports: [ TP MII ]
++ Supported link modes: 10baseT/Half 10baseT/Full
++ 100baseT/Half 100baseT/Full
++ Supports auto-negotiation: Yes
++ Advertised link modes: 10baseT/Half 10baseT/Full
++ 100baseT/Half 100baseT/Full
++ Advertised auto-negotiation: No
++ Speed: 10Mb/s
++ Duplex: Full
++ Port: MII
++ PHYAD: 1
++ Transceiver: internal
++ Auto-negotiation: off
++ Current message level: 0x00000000 (0)
++ Link detected: no
++
++
++The "PHYAD" field shows the current PHY address.
++
++
++
++Usage example
++1) show port1 info
++# echo 1 > /proc/rt2880/gmac # change phy address to 1
++# ethtool eth2
++
++2) show port0 info
++# echo 0 > /proc/rt2880/gmac # change phy address to 0
++# ethtool eth2
