NOTE: BBR *must* be used with the fq qdisc ("man tc-fq") with pacing
enabled, since pacing is integral to the BBR design and
implementation. BBR without pacing would not function properly, and
may incur unnecessary high packet loss rates.

Does it work with fq_codel?

Good question. Since fq_codel does not (currently) implement pacing,
it would not be sufficient to get the required behavior.
