The documentation doesn't match the code though. Almost, but it's off by one.
I can submit a patch instead to change the docs, though it's not clear the
divergence between code and docs was intended in the first place.

(diffserv8 also needs a description in the cake manpage, I'll send a patch
for that once the order is clarified)

Cheers,
