  21  * --------  --------  ------------------------------------------------------
  22  * 04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
  23  * 10-31-07  02.00.01  Fixed name for pMpi2SCSITaskManagementRequest_t.
  24  * 12-18-07  02.00.02  Modified Task Management Target Reset Method defines.
  25  * 02-29-08  02.00.03  Added Query Task Set and Query Unit Attention.
  26  * 03-03-08  02.00.04  Fixed name of struct _MPI2_SCSI_TASK_MANAGE_REPLY.
  27  * 05-21-08  02.00.05  Fixed typo in name of Mpi2SepRequest_t.
  28  * 10-02-08  02.00.06  Removed Untagged and No Disconnect values from SCSI IO
  29  *                     Control field Task Attribute flags.
  30  *                     Moved LUN field defines to mpi2.h becasue they are
  31  *                     common to many structures.
  32  * 05-06-09  02.00.07  Changed task management type of Query Unit Attention to
  33  *                     Query Asynchronous Event.
  34  *                     Defined two new bits in the SlotStatus field of the SCSI
  35  *                     Enclosure Processor Request and Reply.
  36  * 10-28-09  02.00.08  Added defines for decoding the ResponseInfo bytes for
  37  *                     both SCSI IO Error Reply and SCSI Task Management Reply.
  38  *                     Added ResponseInfo field to MPI2_SCSI_TASK_MANAGE_REPLY.
  39  *                     Added MPI2_SCSITASKMGMT_RSP_TM_OVERLAPPED_TAG define.
  40  * 02-10-10  02.00.09  Removed unused structure that had "#if 0" around it.
  41  * 05-12-10  02.00.10  Added optional vendor-unique region to SCSI IO Request.
  42  * 11-10-10  02.00.11  Added MPI2_SCSIIO_NUM_SGLOFFSETS define.
  43  * 11-18-11  02.00.12  Incorporating additions for MPI v2.5.
  44  * 02-06-12  02.00.13  Added alternate defines for Task Priority / Command
  45  *                     Priority to match SAM-4.
  46  *                     Added EEDPErrorOffset to MPI2_SCSI_IO_REPLY.
  47  * 07-10-12  02.00.14  Added MPI2_SCSIIO_CONTROL_SHIFT_DATADIRECTION.
  48  * 04-09-13  02.00.15  Added SCSIStatusQualifier field to MPI2_SCSI_IO_REPLY,
  49  *                     replacing the Reserved4 field.
  50  * 11-18-14  02.00.16  Updated copyright information.
  51  * 03-16-15  02.00.17  Updated for MPI v2.6.
  52  *                     Added MPI26_SCSIIO_IOFLAGS_ESCAPE_PASSTHROUGH.
  53  *                     Added MPI2_SEP_REQ_SLOTSTATUS_DEV_OFF and
  54  *                     MPI2_SEP_REPLY_SLOTSTATUS_DEV_OFF.
  55  * 08-26-15  02.00.18  Added SCSITASKMGMT_MSGFLAGS for Target Reset.
  56  * 12-18-15  02.00.19  Added EEDPObservedValue added to SCSI IO Reply message.
  57  * 01-04-16  02.00.20  Modified EEDP reported values in SCSI IO Reply message.
