  *   Notes:
  *   On some systems dropping root capability allows the process to be
  *   dumped, traced or debugged.
  *   If someone traces this program, they get control of a raw socket.
  *   Linux handles this safely, but beware when porting this program.

  *   An alternative to needing 'root' is using a UDP broadcast socket, however
  *   doing so only works with adapters configured for unicast+broadcast Rx
  *   filter.  That configuration consumes more power.
