  14  *  Date      Version   Description
  15  *  --------  --------  ------------------------------------------------------
  16  *  04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
  17  *  10-31-07  02.00.01  Fixed name for pMpi2SCSITaskManagementRequest_t.
  18  *  12-18-07  02.00.02  Modified Task Management Target Reset Method defines.
  19  *  02-29-08  02.00.03  Added Query Task Set and Query Unit Attention.
  20  *  03-03-08  02.00.04  Fixed name of struct _MPI2_SCSI_TASK_MANAGE_REPLY.
  21  *  05-21-08  02.00.05  Fixed typo in name of Mpi2SepRequest_t.
  22  *  10-02-08  02.00.06  Removed Untagged and No Disconnect values from SCSI IO
  23  *                      Control field Task Attribute flags.
  24  *                      Moved LUN field defines to mpi2.h because they are
  25  *                      common to many structures.
  26  *  05-06-09  02.00.07  Changed task management type of Query Unit Attention to
  27  *                      Query Asynchronous Event.
  28  *                      Defined two new bits in the SlotStatus field of the SCSI
  29  *                      Enclosure Processor Request and Reply.
  30  *  10-28-09  02.00.08  Added defines for decoding the ResponseInfo bytes for
  31  *                      both SCSI IO Error Reply and SCSI Task Management Reply.
  32  *                      Added ResponseInfo field to MPI2_SCSI_TASK_MANAGE_REPLY.
  33  *                      Added MPI2_SCSITASKMGMT_RSP_TM_OVERLAPPED_TAG define.
  34  *  02-10-10  02.00.09  Removed unused structure that had "#if 0" around it.
  35  *  05-12-10  02.00.10  Added optional vendor-unique region to SCSI IO Request.
  36  *  11-10-10  02.00.11  Added MPI2_SCSIIO_NUM_SGLOFFSETS define.
