 *  ---------------
 *
 *  Date      Version   Description
 *  --------  --------  ------------------------------------------------------
 *  04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
 *  06-26-07  02.00.01  Added Clear All Persistent Operation to SAS IO Unit
 *                      Control Request.
 *  10-02-08  02.00.02  Added Set IOC Parameter Operation to SAS IO Unit Control
 *                      Request.
 *  10-28-09  02.00.03  Changed the type of SGL in MPI2_SATA_PASSTHROUGH_REQUEST
 *                      to MPI2_SGE_IO_UNION since it supports chained SGLs.
