fq_codel and/or cake? Shaping?

[dtaht]

I am always interested primarily in the nature of the fair queuing/aqm and shaper within a given offload engine.

I am curious if cake - or fq_codel - like functionality is embedded here? We know codel can be made to run in p4, and we put fq_codel into OVS long ago, but are y'all using it?

our primary use case is in per customer ISP shaping, where cake is the winner (in software), but we have not been able to
scale it much past 20k users and 100Gbit yet.
