So static functions should never be documented? I'm playing devil's
advocate, but still:

I don't think this is the right place for source code documentation. The
intended audience are users, and I wouldn't expect a developer to search
in there. On the other hand, that description would indeed benefit from
a review: Apart from omitting noqueue, it neither mentions leaf qdiscs.
I'll fix this.

Thanks, Phil
