The best place to find examples of broadcasting network
code is in the 4.2 rwhod code.

A large portion of this code (the configure() function, to be exact)
determines what interfaces are available and if they support
hardware broadcast or not.  Once all the "neighbors" (network
and point-point interfaces) have been collected, broadcasting
is done by sending to each neighbor.  Neighbor addresses
are either broadcast (if the HW supports it) or the
destination address of a point to point connection.
