rc.conf: tcp_drop_synfin option

	Hello everyone!

	I have an tcp_drop_synfin="yes" option in my rc.conf, but it doesn't work correct. Here is the dmesg -a part:

        [...]
        Additional routing options:
         ignore ICMP redirect=3DYES
         log ICMP redirect=3DYES
         drop SYN+FIN packets=3DYES
        sysctl:
        unknown oid 'net.inet.tcp.drop_synfin'
        [...]

	I've been thinking about making a patch for it (/etc/rc.d/routing, lines 22-127), but i just didn't find something in `sysctl -a` list that can be used. If this option removed, then may be the lines 124-125 in /etc/rc.d/routing should be changed (something as in attach)? I'm interested in making patch for it :-)
