-m owner & -j MARK problem

[Radu Anghel <eu@xxxxxxxxxxx>]

what's wrong with the following command?

[root:pts/5][~]# iptables -t mangle -A PREROUTING -i eth0 -m owner
--gid-owner 101 -j MARK --set-mark 101
iptables: Invalid argument

[root:pts/5][~]# uname -r
2.6.1
[root:pts/5][~]# iptables -V
iptables v1.2.9
