Subject: [Bloat] Measurement tool to detect fair queuing

I was wondering if my cable modem supports fair queuing, so I wrote a
simple measurement tool. It can test for fq_codel, cake and fq (and
possibly more): https://github.com/muxamilian/fq-detection-simple
In my simple testbed it achieves an accuracy of close to 100%. A limitation
is that the tool struggles to saturate the link for large bandwidths (> 1
Gbit/s) and in this case the measurement will be inconclusive.
Hope it might be useful for some of you.
