Cven-
  Thanks for the input, but I just went ahead and build one for the mipsel 
platform.   If anyone wants it, it's at http://gw.wildcatwireless.net/ping

Anyway, I did this from the .47 router:
(spam-protected):~# ./ping -b 192.168.7.255
WARNING: pinging broadcast address
PING 192.168.7.255 (192.168.7.255) 56(84) bytes of data.

--- 192.168.7.255 ping statistics ---
8 packets transmitted, 0 received, 100% packet loss, time 7017ms

and saw this at the .1 router:
(spam-protected):~# tcpdump -i eth1 host 192.168.7.47 and port not ssh
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 96 bytes
10:51:52.138900 IP router-47 > 192.168.7.255: icmp 64: echo request seq 1
10:51:53.160077 IP router-47 > 192.168.7.255: icmp 64: echo request seq 2
10:51:54.152961 IP router-47 > 192.168.7.255: icmp 64: echo request seq 3
10:51:55.152807 IP router-47 > 192.168.7.255: icmp 64: echo request seq 4
10:51:56.165460 IP router-47 > 192.168.7.255: icmp 64: echo request seq 5
10:51:57.152707 IP router-47 > 192.168.7.255: icmp 64: echo request seq 6
10:51:58.152757 IP router-47 > 192.168.7.255: icmp 64: echo request seq 7
10:51:59.152669 IP router-47 > 192.168.7.255: icmp 64: echo request seq 8


Which is pretty convincing evidence that the broadcast ping is being sent over 
the air.  I would think that ARP resolution would fail, as well, if broadcast 
didn't work.  So, now why won't OLSR broadcast the HELLO packets such that 
everyone can hear them?
