 The submitter may be interested in the following socket option documented
 in ip(4);
 
      If the IP_ONESBCAST option is enabled on a SOCK_DGRAM or a SOCK_RAW
      socket, the destination address of outgoing broadcast datagrams on that
      socket will be forced to the undirected broadcast address,
      INADDR_BROADCAST, before transmission.  This is in contrast to the
      default behavior of the system, which is to transmit undirected broad-
      casts via the first network interface with the IFF_BROADCAST flag set.
 
 Sample code is present in the ip(4) man page.
