easy... you can erase your tc config at the root level :I was not aware that these dependancies were well-maintained in kernel-space. Thank-you.
# tc qdisc del $device root
That will erase the main qdisc discipline in $device. Since all classes, cbqs/sfqs , filters, etc. hang from that one , all of them will be removed too.
