Frank,

The hardware that Route10 is based off of doesn’t support FQ Codel nor CAKE at all, so everything is done in software on our 5.4 Linux kernel. It works great, though. In some instances it’s the only way to max out a PPPoE connection and have optimal latency.

It doesn’t look like our ethernet driver supports BQL at all, so we haven’t tried that yet, but as is, it absolutely eliminates high latency if tuned properly.

How's hardware-offloading of FQ_CoDel looking on these “prosumer” equipment these days? I haven't kept up over a year on this topic."

This is just for the "Route 10" rather than their APs, and they reported getting about 2.5Gbps throughput with CAKE enabled. They do correctly note that the hardware-accelerated forwarding path is disabled for the interface where CAKE is turned on.
