Without checking in code, it seems the timout for DHCP elapses before
the answer arrives. This confirms Fabio's tests, that is something
related to the network. Some boards have set CONFIG_ARP_TIMEOUT to a
higher value as default (200 instead of 5 mSec). Maybe it is related,
maybe not...you need to sniff your network ;-)
