My observations from the business is that FQ just isn't a thing, in 
reality.

I run CAKE myself here on my OpenWrt box and it works great, but I have 
yet to find a commercially available box used by ISPs or something that is 
a big-seller in electronics stores that use FQ_anything, or is even flow 
aware when it comes to forwarding.

I have heard nothing about FQ being implemented in packet accelerators. I 
do hear about people wanting to turn on things that control delay/buffer 
fill, but this is still single queue with no flow-aware anything.

Do we have numbers on how much FQ is actually out there? If we don't, can 
we measure it? Anyone know of devices shipping or being designed that does 
FQ of some kind?
