Subject: [Patch net-next 0/5] net_sched: introduce static flags for qdisc's

The main goal of this patchset is to improve the behavior of setting
the default qdisc. Current behavior has no error check, no check for
ingress and _can_ crash the kernel with some buggy implementation.

We only have flags for each instance of qdisc's, for flags like
if a qdisc is a fifo qdisc, they can simply be moved into qdisc->ops,
as shown by patch 1, 2, 5. Patch 4 just uses this for error checking
when setting default qdisc.

  net_sched: use a flag to indicate fifo qdiscs instead of the name

  net_sched: move ingress flag into qdisc ops
