... ok, this doesn't work, but it gave me an idea.

1. configure a transfer network x.x.x.1/30
2. configure a static arp entry for x.x.x.2
3. "ping x.x.x.2 repeat 10000 timeout 0"

then look at the interface counters:

     9941 packets input, 1173347 bytes, 0 no buffer
     Received 1 broadcasts (0 IP multicasts)
     0 runts, 0 giants, 0 throttles 
     163 input errors, 163 CRC, 0 frame, 0 overrun, 0 ignored
     0 watchdog, 0 multicast, 0 pause input
     0 input packets with dribble condition detected
     10011 packets output, 1181607 bytes, 0 underruns

... sufficient to see "here be problems" :)

thanks,

gert
