That doesn't sound as if it is a problem with the SNTP code. Did you try 
any other traffic, like a TCP client or another UDP application? Can you 
ping your device? You should check for received ARP requests (set a 
breakpoint to etharp_arp_input and see if update_arp_entry finds the 
pending entry with your queued packet).
