//   47 //  DESCRIPTION:
//   48 //      Used by a coordinator in a non-beacon network to transmit a single beacon upon a beacon request.
//   49 //      Unlike the beacon transmission in mac_beacon_handler.c, this beacon is transmitted as a regular
//   50 //      packet, and does not involve timing adjustments, etc.
//   51 //
//   52 //  RETURN VALUE:
//   53 //      BOOL
//   54 //          The transmission was initiated
