While testing my rewrite of Redboot DHCP support, I've noticed that
Redboots "ping" support is also broken.  Redboot responds to ICMP echo
requests that it shouldn't.

Redboot will respond to ICMP echo requests _before_ it has received an
IP address from the BOOTP/DHCP server.  The destination IP address in
the ICMP echo packet _does_not_match_ Redboot's IP address, but it
responds anyway with a source IP address of

Is this behavior intentional?

If so, why?
