41 * mimd_t : Old style ioctl packet structure (deprecated)

45 * @fca :
46 * @opcode :
47 * @subopcode :
48 * @adapno :

51 * @length :
52 * @mbox :

54 * @data :
55 * @pad :
56 *
57 * Note : This structure is DEPRECATED. New applications must use
58 * : uioc_t structure instead. All new hba drivers use the new
59 * : format. If we get this mimd packet, we will convert it into
60 * : new uioc_t format and send it to the hba drivers.
