[LARTC] Consider r2q change, why !?

Hi,

My system always complain with the warning below :
HTB: quantum of class 10099 is small. Consider r2q change.

I simply do not understand why...

Below my tc commands :
/sbin/tc qdisc del dev eth0 root
/sbin/tc qdisc add dev eth0 root handle 1 htb default 99

/sbin/tc class add dev eth0 parent 1: classid 1:2 htb rate 128Kbit

/sbin/tc class add dev eth0 parent 1:2 classid 1:10 htb rate 80Kbit ceil
128Kbit prio 0
/sbin/tc qdisc add dev eth0 parent 1:10 handle 10 sfq perturb 10
/sbin/tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip
dst ***.***.***.*** classid 1:10

/sbin/tc class add dev eth0 parent 1:2 classid 1:99 htb rate 48Kbit ceil
48Kbit prio 7
/sbin/tc qdisc add dev eth0 parent 1:99 handle 99 sfq perturb 10

My default class quantum (99) is correct I guess :  quantum is >
1500 (my MTU).
If I change the rate of my default class to something >= 79 Kbit then it
work without any warning !?!?

I am just looking for an explanation as I'm lost here...

FYI :
#  tc -V
tc utility, iproute2-ss001007
#  uname -r
2.4.26
#  ip link sh eth0
3: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc htb qlen 1000
    link/ether 00:40:63:c9:b3:32 brd ff:ff:ff:ff:ff:ff

Thanks,
Yacine.
