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.
