   *  Version History
   *  ---------------
   *
   *  Date      Version   Description
   *  --------  --------  ------------------------------------------------------
   *  04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
   *  10-31-07  02.00.01  Fixed name for pMpi2SCSITaskManagementRequest_t.
   *  12-18-07  02.00.02  Modified Task Management Target Reset Method defines.
   *  02-29-08  02.00.03  Added Query Task Set and Query Unit Attention.
   *  03-03-08  02.00.04  Fixed name of struct _MPI2_SCSI_TASK_MANAGE_REPLY.
   *  05-21-08  02.00.05  Fixed typo in name of Mpi2SepRequest_t.
   *  10-02-08  02.00.06  Removed Untagged and No Disconnect values from SCSI IO
   *                      Control field Task Attribute flags.
   *                      Moved LUN field defines to mpi2.h becasue they are
   *                      common to many structures.
   *  05-06-09  02.00.07  Changed task management type of Query Unit Attention to
   *                      Query Asynchronous Event.
   *                      Defined two new bits in the SlotStatus field of the SCSI
   *                      Enclosure Processor Request and Reply.
   *  10-28-09  02.00.08  Added defines for decoding the ResponseInfo bytes for
   *                      both SCSI IO Error Reply and SCSI Task Management Reply.
   *                      Added ResponseInfo field to MPI2_SCSI_TASK_MANAGE_REPLY.
   *                      Added MPI2_SCSITASKMGMT_RSP_TM_OVERLAPPED_TAG define.
   *  02-10-10  02.00.09  Removed unused structure that had "#if 0" around it.
   *  05-12-10  02.00.10  Added optional vendor-unique region to SCSI IO Request.
   *  11-10-10  02.00.11  Added MPI2_SCSIIO_NUM_SGLOFFSETS define.
   *  11-18-11  02.00.12  Incorporating additions for MPI v2.5.
   *  02-06-12  02.00.13  Added alternate defines for Task Priority / Command
   *                      Priority to match SAM-4.
   *                      Added EEDPErrorOffset to MPI2_SCSI_IO_REPLY.
   *  07-10-12  02.00.14  Added MPI2_SCSIIO_CONTROL_SHIFT_DATADIRECTION.
   *  04-09-13  02.00.15  Added SCSIStatusQualifier field to MPI2_SCSI_IO_REPLY,
   *                      replacing the Reserved4 field.
