No, it isn't but all the other functions have hw offloads and the CoDel
numbers shown are when you turn hw offloads off, basically only running it
in CPU forwarding mode. That's when you get those kinds of numbers (~800
megabit/s).
When enabling SQM on their USG3 you get ~100 megabit/s of throughput,
because it has a very slow CPU (but has plenty of offloads, so full gig
with offloads enabled works well, but then you don't get any SQM/DPI).
