Thank you for you help.
Here is the HTB

echo Clean all the tc setup
./tc qdisc del dev lo root

./tc qdisc add dev lo root handle 1: htb default 12

./tc class add dev lo parent 1: classid 1:1 htb rate 100kbps ceil 100kbps
./tc class add dev lo parent 1:1 classid 1:2 htb rate 40kbps ceil 100kbps
./tc class add dev lo parent 1:2 classid 1:10 htb rate 30kbps ceil 100kbps
prio 0
./tc class add dev lo parent 1:2 classid 1:11 htb rate 10kbps ceil 100kbps
prio 1
./tc class add dev lo parent 1:1 classid 1:12 htb rate 60kbps ceil 100kbps

echo qdisc
./tc qdisc add dev lo parent 1:10 handle 20: pfifo limit 5
./tc qdisc add dev lo parent 1:11 handle 30: pfifo limit 5
./tc qdisc add dev lo parent 1:12 handle 40: sfq perturb 10
