I don't think we should set any flag for the netapp behaviour.  It might
be stretching the standard a little, but it's not completely odd and I
can't think of anything bad that could hapen if we do it unconditonally.

Something like:

	if ((result[0] >> 5) == 1 || starget->some_flag) &&
	    (result[0] & 0x1f) == 0x1f) {
	    	SCSI_LOG_SCAN_BUS(3, printk(KERN_INFO
			"scsi scan: peripheral device type"
			" of 31, no device added\n"));
		res = SCSI_SCAN_TARGET_PRESENT;
		goto out_free_result;
	}
