I can run an Ookla test in the middle of the night with LibreQoS off for a
bit.
From what I recall - without Libre we see download bloat of 300ms or so.
With Libre, it's gone. On waveform we see 0ms added bloat each direction
for most clients.

And I like the "monitor only" mode idea.
Perhaps we could create the HTB tree, but just not attach the CAKE qdisc?
Technically even HTB could reduce latency by itself on overloaded APs , so
it wouldn't be true passive monitoring, but it would allow us to compare
the before/after of CAKE while still having qdiscs we can point
cpumap-pping to.

Alternatively, maybe we could use eBPF PPing just for this passive
monitoring period?
