Probably it is. Try a sniffer (ethereal, tcpdump) on the host to see if
anything is transmitted by the board.

Why do you think that the problem is still at the hardware level? What
are the board's IP address, MAC address, subnet mask, etc. (just type
printenv). You write that 172.18.100.54 exists but you don't write
anything about the host to which this address belongs. Is it a Linux
machine? Does it respond to pings at all? What's about subnets? There
are too many possible reasons for ping failure.
