Please don't mix up ethernet address (== MAC address) and IP address. Of 
course you can set ip addresses (and should if you don't use dhcp/bootp). But 
you have to configure valid ethernet addresses too. If you don't have an 
ethernet address pool, you can use the "tools/gen_eth_addr" tool to create a 
random valid eth address for testing.

And what does "mii info" show (without parameter)?

What is the value of CONFIG_PHY_ADDR in your board config file?
