Hi If not ataching any qdisc disc to a cba/htb leaf class what does that mean? There will be a default fifo style queue ? Or there will be no queue at all on the leaf class? Also if deleting any existing qdisc on a device (tc qdisc del dev eth0 root) what it will happen with the packets destined to go out on that interface? My tests show that the packets still go out only that I am not sure if there is any queue on that device.
