+
+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
