Hi, Dave here.

I recommend using a small box running LibreQoS adjacent to the big router. Large-scale routers based on Application-Specific ICs do a wonderful job, but are hard to change. Having a transparent fix in an inexpensive device now is way better than waiting and hoping that the router vendor can update their ASICs (:-))

I emphasised your problem in a video about the article, at https://vimeo.com/1017926413
