Thank you for your help.

It generates this script : 

tc qdisc add dev eth0 handle 1:0 root htb default 2
tc class add dev eth0 parent 1:0 classid 1:1 htb rate 75000bps ceil \
75000bps
tc class add dev eth0 parent 1:0 classid 1:2 htb rate 125000bps
tc filter add dev eth0 parent 1:0 protocol all prio 1 u32 match u32 \
0xa000001 0xffffffff at 12 classid 1:1

But I thought it was necessary to have a "root" htb class on the top of
the hierarchy to get it working as expected. Is that true ? 

Thanks
