U-boot will not answer to a remote ping (no interrupt etc).
But you can send a ping from U-boot to a remote target 
if you have CFG_CMD_PING enabled in your configuration.

Did you enable "IP: kernel level autoconfiguration" in your 
Linux kernel? I use the "bootargs" to give the Linux kernel 
the appropriate parameters for the eth interfaces.
( setenv bootargs
ip=$(ipaddr):$(serverip):$(gatewayip):$(netmask):$(hostname):eth0:off )

Torsten
