Like that:
tc qdisc add dev eth0 root handle 1: prio

tc qdisc add dev eth0 root handle 1: prio
## This *instantly* creates classes 1:1, 1:2, 1:3

Like that:
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32

>Each class has 1 qdisc attached to it.  This is (by

e.g.
tc filter add dev eth0 protocol ip parent 1:1 prio 2 u32
                                           ^^     ^^
                                          band1   priority 2 ???????????

What have i used above? None of cbj tbf or htb, have I?
