[LARTC] HTB & police filters

[Mihai RUSU <dizzy@roedu.net>]

Hi

Im playing with HTB and police filters. It seems that the drop action
doesnt work with htb (I think it sends the traffic to the "default"
configured class).

#!/bin/bash

tc=/sbin/tc

$tc qdisc del dev eth0 root
$tc qdisc add dev eth0 root handle 1: htb default 20

$tc class add dev eth0 parent 1: classid 1:1 htb rate 100Mbit burst 15k

$tc class add dev eth0 parent 1:1 classid 1:10 htb rate 128Kbit burst 15k
$tc class add dev eth0 parent 1:1 classid 1:20 htb rate 256Kbit ceil 100Mbit burst 15k

$tc class add dev eth0 parent 1:10 classid 1:100 htb rate 64Kbit burst 15k
$tc class add dev eth0 parent 1:10 classid 1:200 htb rate 128Kbit burst 15k

$tc filter add dev eth0 protocol ip parent 1: pref 5 u32 match ip dst \
1.2.3.4 flowid 1:200 police drop rate 64Kbit burst 15k

It seems that the filter matches the defined rate and calls enqueue() for
class 1:200, but after that the overlimit traffic it sends to the
"default" 1:20 defined htb class. If I want this I could use "continue"
but NOT drop. Is this a bug? :)
