Yes I tried recently, according to your suggestion.
I submitted 'tcpdump -i cipdb0' on 192.168.3.1.
When I ping it from 192.168.3.2 I get no packets in tcpdump!
But when I ping 192.168.3.255 (bcast) from 192.168.3.2 I get the following 
packets:
11:35:50.543028 192.168.3.2 > 192.168.3.255: icmp: echo request
11:35:50.543162 arp who-has 192.168.3.2 tell 192.168.3.1
But no reply to either.
This tell me that IP broadcast gets through the link,
but arp doesn't work beacuse ethernet broadcast doesn't go through the link.
Am I right? What can I do?
