When a packet end up in the root class (or a non-leaf class), strange things
can happen. In htb3.4 or so, the nic hanged when you put 1 packet in a
non-leaf class. Devik fixed it in a later release. You don't know how the
packet is handled. It's better to create an extra class and make it the
default class.
