[BB] So do you suspect that any of the CE-marking in traffic not 
traversing their backhaul FQ-CoDel boxes is from a FIFO ECN-enabled AQM?

Or is this ISP particularly attractive to users into free and 
open-source software, in which case I would have thought the CE marking 
is most likely to be coming from FQ-CoDel? Or can we just not really tell?

As the rest of your email changed subject to tunnels, I've split that 
into a separate thread.
