Subject: [net-next PATCH 0/3] net: sched: allow switching qdisc to noqueue intuitively

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.

Phil Sutter (3):
  net: sched: make noqueue_qdisc non-static
  net: sched: allocate a handle to default qdiscs
  net: sched: fall back to noqueue when removing root qdisc
