+
+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
