Thanks for the information. But I read some where that for the Lab testing purpose that I can give the IP address!!!!!
I am able to read the PHY inforamtion by command mii info 0x01<PHY Addr>. Following is the info....
=> mii info 0x01
PHY_PHYIDR2 @ 0x1 = 0x5c90
PHY_PHYIDR[1,2] @ 0x1 = 0x20005c90
PHY_BMCR value is 0x2100
PHY 0x01: OUI = 0x80017, Model = 0x09, Rev = 0x00, 100baseT, FDX
But my Link LED is not glowing at all. Always my Link status shows "Not Active" can anyone throw some light for me.....

Did you configure the PHY address correctly? What does "mii info" show? how
did you configure the PHY address in your board config file?
