Hi, Everybody.

In FreeBSD, I write a program in python(2.4.4 & 2.5), which include a
broadcast routine.

But, I send the broadcast in FreeBSD, it's different from others OS, like
Windows, Linux...

When I send the broadcast in FreeBSD with address 255.255.255.255, the
packet can not be received by other OS.

But I send the broadcast in non-BSD System with address 255.255.255.255, all
OS got it.

When I send the broadcast in FreeBSD with address like 192.168.1.255, all OS
got it.

I have seen the Python socket implement, there is no added option for
FreeBSD, but why? Why it is different?
