DRR example, how to replace SFQ

DRR example, how to replace SFQ

[Denys Fedoryschenko]

If i understand right, it must look like this to simulate SFQ 
This example with just 2 "queues".

tc qdisc add dev eth0.100 root handle 1: htb

tc class add dev eth0.100 parent 1: classid 1:1 htb rate 15Kbit ceil 15Kbit

tc qdisc add dev eth0.100 parent 1:1 handle 2: drr

tc class add dev eth0.100 parent 2: classid 2:1 drr quantum 1600
tc class add dev eth0.100 parent 2: classid 2:2 drr quantum 1600

tc qdisc add dev eth0.100 parent 2:1 handle 10: bfifo 9000
tc qdisc add dev eth0.100 parent 2:2 handle 11: bfifo 9000

tc filter add dev eth0.100 parent 1: protocol ip prio 5 u32 match u32 0 0 
flowid 1:1

tc filter add dev eth0.100 parent 2: protocol ip prio 10 handle 1 flow keys 
dst divisor 2 baseclass 2:1

Is it correct?

Generally looks OK, but examples from cls_flow changelog could be
followed:
