Maxim Konovalov 5a47f206a1 o Some programs could send broadcast/multicast traffic to ipfw
pseudo-interface.  This leads to a panic due to uninitialized
if_broadcastaddr address.  Initialize it and implement ip_output()
method to prevent mbuf leak later.

ipfw pseudo-interface should never send anything therefore call
panic(9) in if_start() method.
