You can't set the max burst size smaller than the normal burst size.
So at the least it has to be the same.
It goes something like: guarantee the amount and you could burst to normal
burst. From normal burst to max burst= excess and there are great chances
of dropping. If normal = max, then there's no excess. Above the max is
violate which rate-limit doesn't support
