I use ethloop also and 0x10010 is class 1:10, 0x10011 is class 1:11.
(ethloop is a tool that can be used to test htb, see htb home page).
Example :
tc qdisc del dev lo root
ifconfig lo mtu 1500
tc qdisc add dev lo root handle 1: htb default 10
TC="tc class add dev lo parent"
$TC 1: classid 1:1 htb rate 100kbps
$TC 1:1 classid 1:10 htb rate 40kbps ceil 100kbps
$TC 1:1 classid 1:11 htb rate 60kbps ceil 100kbps
tc qdisc add dev lo parent 1:10 pfifo
tc qdisc add dev lo parent 1:11 pfifo
0 i 0 lo
0 i 1 lo
0 P 0 0x10010
0 P 1 0x10011
0 S 0 1500
0 S 1 1500
# start all flows
0 R 0 120k
0 R 1 120k
12000 X 0 0
