Here is a side note about queueing disciplines and traffic control in general: when a packet is ready to be sent on the network, it doesn't means that it has to reach all queues of the trees before beeing sent. AFAIK, it's wrong to assume that the whole traffic control system is a flow of queueing to pass through. The reason is that if the NIC is ready to send the next packet, tc will try to satisfy the NIC as soon as possible. As such, it can and will pick the next packet to send from anywhere of the tree of the queueing disciplines. I don't know if you have a configuration problem or if you had that in mind while testing your configuration but I hope this might help to understand why the filter was not reached in your tests.
