This patch series improves the integration of the noqueue qdisc to become the fallback queueing if no other is attached to an interface. Before it was rather an add-on, a simpler alternative to a FIFO if no congestion is expected or possible. It has become the default qdisc for virtual interfaces, and could be attached by this mechanism only (through removing the root qdisc after having set tx_queue_len to zero for interfaces not defaulting to noqueue otherwise).
This series does not change the default qdisc chosen for new interfaces, but upon removal of the root qdisc from an interface, the kernel won't fall back to the default but to noqueue instead. Changes since v1: - Leave qdisc_create_dflt() alone as it is used in sch_htb.c as well. Instead allocate the handle in attach_default_qdiscs() and attach_one_default_qdisc().
