Use an HTB/CBQ class at the top with 1mbit limit. (HTB is easier).
Direct all traffic to this class. You do not need to use mark here.
Fit your four PRIO classes under the HTB class, if you want, and filter
traffic based on marks.

Ok, I tried it (with a tbf), now my bandwidth is well limitated, but my filters doesn't seem to work, all the packets go in 400: . Here is my script :

tc qdisc add dev eth2 root handle 1:0 tbf rate 1mbit buffer 1600 limit 10000
tc qdisc add dev eth2 parent 1:0 handle 10: prio bands 4 priomap 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3
tc qdisc add dev eth2 parent 10:1 handle 100: sfq
tc qdisc add dev eth2 parent 10:2 handle 200: sfq
tc qdisc add dev eth2 parent 10:3 handle 300: sfq
tc qdisc add dev eth2 parent 10:4 handle 400: sfq
tc filter add dev eth2 parent 10: prio 1 protocol ip handle 0x1 fw flowid 100:
tc filter add dev eth2 parent 10: prio 2 protocol ip handle 0x2 fw flowid 200:
tc filter add dev eth2 parent 10: prio 3 protocol ip handle 0x3 fw flowid 300:

I've tried to replace parent 10: by parent 1:, but it makes an error (very explicit, like all the tc errors).

Thank you in advance,
