 *  ---------------
 *
 *  Date      Version   Description
 *  --------  --------  ------------------------------------------------------
 *  05-08-00  00.10.01  Original release for 0.10 spec dated 4/26/2000.
 *  06-06-00  01.00.01  Update version number for 1.0 release.
 *  06-22-00  01.00.02  Added _MSG_TARGET_CMD_BUFFER_POST_REPLY structure.
 *                      Corrected DECSRIPTOR typo to DESCRIPTOR.
 *  11-02-00  01.01.01  Original release for post 1.0 work
 *                      Modified target mode to use IoIndex instead of
 *                      HostIndex and IocIndex. Added Alias.
 *  01-09-01  01.01.02  Added defines for TARGET_ASSIST_FLAGS_REPOST_CMD_BUFFER
 *                      and TARGET_STATUS_SEND_FLAGS_REPOST_CMD_BUFFER.
 *  02-20-01  01.01.03  Started using MPI_POINTER.
 *                      Added structures for MPI_TARGET_SCSI_SPI_CMD_BUFFER and
 *                      MPI_TARGET_FCP_CMD_BUFFER.
