 *
 *  Version History
 *  ---------------
 *
 *  Date      Version   Description
 *  --------  --------  ------------------------------------------------------
 *  04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
 *  08-31-07  02.00.01  Modifications to RAID Action request and reply,
 *                      including the Actions and ActionData.
 *  02-29-08  02.00.02  Added MPI2_RAID_ACTION_ADATA_DISABL_FULL_REBUILD.
 *  05-21-08  02.00.03  Added MPI2_RAID_VOL_CREATION_NUM_PHYSDISKS so that
 *                      the PhysDisk array in MPI2_RAID_VOLUME_CREATION_STRUCT
 *                      can be sized by the build environment.
 *  07-30-09  02.00.04  Added proper define for the Use Default Settings bit of
 *                      VolumeCreationFlags and marked the old one as obsolete.
 *  05-12-10  02.00.05  Added MPI2_RAID_VOL_FLAGS_OP_MDC define.
