Throttling bandwidth with iptables and tc

[BL4CKFIRE64]

I am trying to limit bandwidth of certain ip addresses on my server. I have been doing hours of reading and not getting very far... So far I believe the iptables command is

ptables -A PREROUTING -s 178.33.23.44 -t mangle -j MARK --set-mark 2
ptables -A PREROUTING -s 178.33.23.45 -t mangle -j MARK --set-mark 2
ptables -A PREROUTING -s 178.33.23.46 -t mangle -j MARK --set-mark 2
ptables -A PREROUTING -s 178.33.23.47 -t mangle -j MARK --set-mark 2

and now I just need the tc command to read those marks and limit bandwidth, I have a gigabit connection and would like to limit each of these ip addresses to 10mbit in and out. Can someone please give me the right command?

This is a good start for traffic shaping:
