Hello,

	I have HTB on IMQ device. My rate does not work as I configured. I
configured 1920kbit/s and I can download only about 290kbit/s (while it
should be the whole bandwidth).
My script:
/sbin/modprobe imq numdevs=1
/usr/local/sbin/tc qdisc del dev imq0 root  2> /dev/null > /dev/null
/usr/local/sbin/tc qdisc del dev imq0 ingress 2> /dev/null > /dev/null
/sbin/ifconfig imq0 down
/usr/local/sbin/iptables -t mangle -D PREROUTING -i eth2 -j IMQ --todev 0
2> /dev/null
/usr/local/sbin/iptables -t mangle -D POSTROUTING -o eth2 -j IMQ --todev 0
2> /dev/null
/usr/local/sbin/tc qdisc add dev imq0 root handle 1: htb default 10
/usr/local/sbin/tc class add dev imq0 parent 1: classid 1:1 htb rate

/usr/local/sbin/iptables -t mangle -A PREROUTING -i eth2 -j IMQ --todev 0
/sbin/ip link set imq0 up

Everything (tested what I did) went to class 1:10
Some stats:
Class statistics:

class htb 1:1 root rate 1920Kbit ceil 1920Kbit burst 4056b/8 mpu 0b cburst

the rate 36918bps was a constant rate for 10 minutes (I copyed with scp a
big file).

	Thanks in advance,
