Hi,

In the past I think the same thing but:

mii info

report that information. ex (take in a past mail)
PHY 0x10: OUI = 0x5043, Model = 0x08, Rev = 0x07,  10baseT, HDX
PHY 0x11: OUI = 0x5043, Model = 0x08, Rev = 0x07,  10baseT, HDX
PHY 0x12: OUI = 0x5043, Model = 0x08, Rev = 0x07,  10baseT, HDX
PHY 0x13: OUI = 0x5043, Model = 0x08, Rev = 0x07, 100baseT, FDX
PHY 0x14: OUI = 0x5043, Model = 0x08, Rev = 0x07,  10baseT, HDX
PHY 0x15: OUI = 0x0000, Model = 0x00, Rev = 0x00,  10baseT, HDX
PHY 0x16: OUI = 0x0000, Model = 0x00, Rev = 0x00,  10baseT, HDX

what code autodetect code pick? And if you have ghost PHYs in the list?
