This sounds sane.

After having to edit every damn file net/sched/ over the weekend
a few things really bugged me.  One of which was how so much logic
is duplicated in the configuration support code.

The worst offender is TCA_RATE, it's scattered all over the place.

If I get ambitious after all the multiqueue bits are sorted I might
try to consolidate some of this stuff.

But definitely, let's not add more of that kind of stuff.
