Yeah, but the filters I pasted are just a test case, my actual setup
(pasted at the bottom of this email) really does require having
filters that properly delegate the traffic.

Tried that too, the packets still aren't going through the SFQ.

The setup:
BW=80
DEV=3Deth1

HBW=3D$(($BW/2))

tc qdisc del dev $DEV root
tc qdisc add dev $DEV root handle 1: htb r2q 1
tc class add dev $DEV parent 1: classid 1:1 htb rate ${BW}kbit ceil ${BW}kb=
it
tc qdisc add dev $DEV parent 1:1 handle 2: prio bands 4
tc qdisc add dev $DEV parent 2:1 handle 10: sfq perturb 10 # Lowlatency
tc qdisc add dev $DEV parent 2:2 handle 20: sfq perturb 10 # Medium Latency
tc qdisc add dev $DEV parent 2:3 handle 30: sfq perturb 10 # Regular
tc qdisc add dev $DEV parent 2:4 handle 40: htb r2q 1      # Bulk

tc class add dev $DEV parent 40: classid 40:1 htb rate ${HBW}kbit ceil ${BW=
}kbit
tc class add dev $DEV parent 40: classid 40:2 htb rate ${HBW}kbit ceil ${BW=
}kbit
tc qdisc add dev $DEV parent 40:1 handle 41: sfq perturb 10
tc qdisc add dev $DEV parent 40:2 handle 42: sfq perturb 10

tc filter add dev $DEV parent 1: protocol ip prio 1 u32 match ip protocol 1=
 0xff flowid 2:1
tc filter add dev $DEV parent 1: protocol ip prio 1 u32 match ip tos 0x10 0=
xff flowid 2:1
tc filter add dev $DEV parent 1: protocol ip prio 1 u32 match ip protocol 6=
 0xff match u8 0x05 0x0f at 0 match u16 0x0000 0xffc0 at 2 match u8 0x10 0x=
ff at 33 flowid 2:1 # Small ACKs

tc filter add dev $DEV parent 1: protocol ip prio 2 handle 1022 fw flowid 4=
0:1  # Bulk1
tc filter add dev $DEV parent 1: protocol ip prio 2 handle 1027 fw flowid 4=
0:2  # Bulk2

tc filter add dev $DEV parent 1: protocol ip prio 3 u32 match ip protocol 6=
 0xff match u8 0x10 0xff at nexthdr+13 flowid 2:1  # All ACKs

tc filter add dev $DEV protocol ip parent 1: prio 999 u32 match ip src 0/0 =
flowid 2:3  # Anything else goes into the Regular category
