Are you able to tftp an image to your board in u-boot?
Get's your ethernet controller initialized after reset?
Using a strange/cheap hub/switch?
In Linux you have always some "ifconfig interface xxxx" stuff
during boot...so adding an "up" statement wouldn't hurt...

setenv netmask x.x.x.x
and if you like:
setenv gatewayip x.x.x.x

Should be...
