[U-Boot-Users] U-boot and IXP425 NPE

I am trying to compile network support for IXP425 NPE

First I got error for undefined CONFIG_PHY_ADDR

I have defined CONFIG_PHY_ADDR

It then compiled and gave me undefined functions: miiphy_read, miiphy_speed, miiphy_duplex

Has anyone successfuly operated IXP425 NPE?
