Hi,
Is it possible to attach another qdisq under a HFSC classfull ?
I try it and the configuraton works :
$TC qdisc add dev $dev root handle 1: hfsc default 30
$TC class add dev $dev parent 1: classid 1:1 hfsc sc rate
${RATE}mbit ul rate ${RATE}mbit
$TC class add dev $dev parent 1:1 classid 1:10 hfsc rt umax 1500b
dmax 30ms rate 200kbit
$TC class add dev $dev parent 1:1 classid 1:20 hfsc rt umax 1500b
dmax 1ms rate 5mbit
$TC class add dev $dev parent 1:1 classid 1:40 hfsc sc rate
${RATE15}mbit ul rate ${RATE}mbit
$TC qdisc add dev $dev parent 1:10 handle 10 sfq perturb 10
$TC qdisc add dev $dev parent 1:20 handle 20 sfq perturb 10
$TC qdisc add dev $dev parent 1:30 handle 30:0 htb default 302
$TC class add dev $dev parent 30:0 classid 30:1 htb rate ${RATE}mbit
burst 15k quantum 60000
$TC class add dev $dev parent 30:1 classid 30:10 htb rate
${RATE15}mbit ceil ${RATE}mbit burst 15k prio 1 quantum 60000
$TC class add dev $dev parent 30:1 classid 30:20 htb rate
${RATE15}mbit ceil ${RATE}mbit burst 15k prio 2 quantum 60000
$TC qdisc add dev $dev parent 30:10 handle 301:0 sfq perturb 10
$TC qdisc add dev $dev parent 30:20 handle 302:0 sfq perturb 10

but when I made a filter for put packets in one of the HTB classes (30:10)
it arrive at the principal HTB class (30) and it sent directly to the
interface.
It didn''t pass by the htb class but the stream go out of the router.
