+ * ---------------
+ *
+ * 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.
+ * 11-18-14  02.00.16  Updated copyright information.
+ * 03-16-15  02.00.17  Updated for MPI v2.6.
+ *                     Added MPI26_SCSIIO_IOFLAGS_ESCAPE_PASSTHROUGH.
+ *                     Added MPI2_SEP_REQ_SLOTSTATUS_DEV_OFF and
+ *                     MPI2_SEP_REPLY_SLOTSTATUS_DEV_OFF.
+ * 08-26-15  02.00.18  Added SCSITASKMGMT_MSGFLAGS for Target Reset.
+ * 12-18-15  02.00.19  Added EEDPObservedValue added to SCSI IO Reply message.
+ * 01-04-16  02.00.20  Modified EEDP reported values in SCSI IO Reply message.
+ * 01-21-16  02.00.21  Modified MPI26_SCSITASKMGMT_MSGFLAGS_PCIE* defines to
+ *                     be unique within first 32 characters.

+ * ---------------
+ *
+ * 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.
+ * 11-18-14  02.00.09  Updated copyright information.
+ * 03-16-15  02.00.10  Updated for MPI v2.6.
+ *                     Added MPI2_SATA_PT_REQ_PT_FLAGS_FPDMA.

+ * ---------------
+ *
+ * Date      Version   Description
+ * --------  --------  ------------------------------------------------------
+ * 04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
+ * 12-18-07  02.00.01  Added Diagnostic Buffer Post and Diagnostic Release
+ *                     structures and defines.
+ * 02-29-08  02.00.02  Modified various names to make them 32-character unique.
+ * 05-06-09  02.00.03  Added ISTWI Read Write Tool and Diagnostic CLI Tool.
+ * 07-30-09  02.00.04  Added ExtendedType field to DiagnosticBufferPost request
+ *                     and reply messages.
+ *                     Added MPI2_DIAG_BUF_TYPE_EXTENDED.
+ *                     Incremented MPI2_DIAG_BUF_TYPE_COUNT.
+ * 05-12-10  02.00.05  Added Diagnostic Data Upload tool.
+ * 08-11-10  02.00.06  Added defines that were missing for Diagnostic Buffer
+ *                     Post Request.
+ * 05-25-11  02.00.07  Added Flags field and related defines to

+ * 07-10-12  02.00.09  Add MPI v2.5 Toolbox Diagnostic CLI Tool Request
+ *                     message.
+ * 07-26-12  02.00.10  Modified MPI2_TOOLBOX_DIAGNOSTIC_CLI_REQUEST so that
+ *                     it uses MPI Chain SGE as well as MPI Simple SGE.
+ * 08-19-13  02.00.11  Added MPI2_TOOLBOX_TEXT_DISPLAY_TOOL and related info.
+ * 01-08-14  02.00.12  Added MPI2_TOOLBOX_CLEAN_BIT26_PRODUCT_SPECIFIC.
+ * 11-18-14  02.00.13  Updated copyright information.
+ * 08-25-16  02.00.14  Added new values for the Flags field of Toolbox Clean
+ *                     Tool Request Message.
+ * 07-22-18  02.00.15  Added defines for new TOOLBOX_PCIE_LANE_MARGINING tool.
+ *                     Added option for DeviceInfo field in ISTWI tool.
+ * 12-17-18  02.00.16  Shorten some defines to be compatible with DOS.
