qos-scripts: Add IPv6 support
This adds IPv6 support to qos-scripts for both tc/qdisc and the iptables classification rules. The tc/qdisc part is accomplished by removing "protocol ip" from the tc command line, causing the rule to be applied to all protocols. The iptables part is accomplished by adding each rule using both iptables and ip6tables. This patch is based on previous work by Ilkka Ollakka and Dominique Martinet. Signed-off-by: Michael Marley <michael@michaelmarley.com> SVN-Revision: 48452
