 * NOTE: Names (typedefs, defines, etc.) beginning with an MPI25 or Mpi25

 *
 * Version History
 * ---------------
 *
 * 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.
 * 05-12-10  02.00.04  Modified some comments.
 * 08-11-10  02.00.05  Added NCQ operations to SAS IO Unit Control.
 * 11-18-11  02.00.06  Incorporating additions for MPI v2.5.
 * 07-10-12  02.00.07  Added MPI2_SATA_PT_SGE_UNION for use in the SATA
 *                     Passthrough Request message.
 * 08-19-13  02.00.08  Made MPI2_SAS_OP_TRANSMIT_PORT_SELECT_SIGNAL obsolete
 *			for anything newer than MPI v2.0.
