I had this problem too. In my case the problem was caused by an 
incorrect port multiplex configuration in U-Boot, see 
CONIFG_SYS_GPS_PORT_CONFIG (I use 0x xxx5xxxx, which corresponds to 
10/100Mbit Eth with MD).

When running any network command under U-Boot the function eth_init() is 
called which sets the port conifg correctly.
