Yes - in ipfr_fastroute and ipflow_fastforward IPFilter calls the
interface output routine directly. I will have to duplicate the check
and functional call from ip_output.c in these functions as well. I'm
afraid I hadn't planned to look at the IPFilter functions until after I
had ip_output working, but it should be straightforward.
