 *    mpi2_init.h Version:  02.00.11
 *
 *  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.
