No - at 90% shaping on ingress, 5/5ms will trigger when the visible queue
has built up to 5ms over a continuous 50ms. At 95%, it'll trigger at 100ms.
Remember, Codel can't see what's in the dumb FIFO on the upstream end of
the link. By the time it triggers, there's potentially a lot of queue there
that it doesn't know about and can't directly measure. That's why it has to
be more aggressive about the queue it can see.
