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

[Cong Wang <xiyou.wangcong@gmail.com>]

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.
