 *
 * 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.
