	To the best of my knowledge, it should work. Maybe you will find
useful removing the `bounded' option, in order to allow everyone using the
maximum bandwidth whenever it is possible.

	Moreover, for traffic shaping you may find useful the
tbf (Tocken Bucket Filter) discipline instead of sfq.

	Try something like 'tc qdisc del dev eth0 del root', the root
qdisc, class and all the children nodes should vanish.
