2574 +Ethtool readme for selecting different PHY address.
2575 +
2576 +Before doing any ethtool command you should make sure the current PHY
2577 +address is expected. The default PHY address is 1(port 1).
2578 +
2579 +You can change current PHY address to X(0~4) by doing follow command:
2580 +# echo X > /proc/rt2880/gmac
2581 +
2582 +Ethtool command also would show the current PHY address as following.
2583 +
2584 +# ethtool eth2
2585 +Settings for eth2:
2586 + Supported ports: [ TP MII ]
2587 + Supported link modes: 10baseT/Half 10baseT/Full
2588 + 100baseT/Half 100baseT/Full
2589 + Supports auto-negotiation: Yes
2590 + Advertised link modes: 10baseT/Half 10baseT/Full
2591 + 100baseT/Half 100baseT/Full
2592 + Advertised auto-negotiation: No
2593 + Speed: 10Mb/s
2594 + Duplex: Full
2595 + Port: MII
2596 + PHYAD: 1
2597 + Transceiver: internal
2598 + Auto-negotiation: off
2599 + Current message level: 0x00000000 (0)
2600 + Link detected: no
2601 +
2602 +
2603 +The "PHYAD" field shows the current PHY address.
2604 +
2605 +
2606 +
2607 +Usage example
2608 +1) show port1 info
2609 +# echo 1 > /proc/rt2880/gmac # change phy address to 1
2610 +# ethtool eth2
2611 +
2612 +2) show port0 info
2613 +# echo 0 > /proc/rt2880/gmac # change phy address to 0
2614 +# ethtool eth2
