This example not approach? 

tc qdisc add dev eth0 root handle 1 htb default 7
tc class add dev eth0 parent 1: classid 1:7 htb rate 500mbit ceil 1000mbit prio 3
tc qdisc add dev eth0 parent 1:7 handle 10: sfq perturb 10

# all traffic go to class 1-7.

# Try group traffic by "src,dst" key

tc filter add dev eth0 protocol ip parent 10: handle 2 flow hash keys src,dst

# all traffic dropped
