Exactly. I'd again like to stress the fact that this configuration works:

	jikos:~ # tc qdisc show
	qdisc tbf 10: dev eth0 root refcnt 2 rate 800Mbit burst 131000b lat 1.0ms 

and this (after performing add/delete operation) doesn't:

	jikos:~ # tc qdisc show
	qdisc tbf 10: dev eth0 root refcnt 2 rate 800Mbit burst 131000b lat 1.0ms 

It's hard to spot a difference (hint: there is none).

Thanks,
