I can answer that: I didn't know of that broadcast ping, but I tested here
on my LAN and it works. The answer is:
that is usefull for manual operation. You just go to any client machine
and ping 10.0.0.255 and you hava a list of everything. I surely will use
it in the future :)

I needed ICMP to be able to respond to broadcast pings for
autoconfiguration.
I added flags: LWIP_BROADCAST_PING and LWIP_MULTICAST_PING that can be
defined
in lwipopts.h if you want broadcast pings. The only patched file is
ipv4/icmp.c
