[SOLVED] understand how traffic control tc works

hi
i'm "trying" to write a new qdisc for tc
i want to understand who calls the dequeue function that is declared
in the static struct Qdisc_ops and defined in the file.c that develop the qdisc
logic.
(i.e. see http://lxr.linux.no/linux+v2.6.33.5/net/sched/sch_tbf.c that implement the token bucket qdisc
who call tbf_dequeue?)
any suggestion will be apreciated!

Please trace through dev_queue_xmit(), net_tx_action() and calls to
__qdisc_run() in net/core/dev.c and net/sched/sch_generic.c.

Hope this helps.
