+/*  void Shm_Convert_packet( &packet )

+ *  This routine is the shared memory locked queue MPCI driver routine
+ *  used to convert the RTEMS's information in a packet from non-native
+ *  format to processor native format.
+ *
+ *  Input parameters:
+ *    packet  - pointer to a packet
+ *
+ *  Output parameters:
+ *    *packet - packet in native format
+ *
+ *  NOTE: Message buffers are not manipulated.
+ *        Endian conversion is currently the only conversion.
