Btw, I guess David owes you one classful(!) dummy(?) scheduler...

    net_sched: add classful multiqueue dummy scheduler
    
    This patch adds a classful dummy scheduler which can be used as root qdisc
    for multiqueue devices and exposes each device queue as a child class.
    
    This allows to address queues individually and graft them similar to regular
    classes. Additionally it presents an accumulated view of the statistics of
    all real root qdiscs in the dummy root.
    
    Two new callbacks are added to the qdisc_ops and qdisc_class_ops:
    
    - cl_ops->select_queue selects the tx queue number for new child classes.
    
    - qdisc_ops->attach() overrides root qdisc device grafting to attach
      non-shared qdiscs to the queues.
