[Codel] Pie not fully implementable on tofino p4

For a codel comparison, see:

https://arxiv.org/pdf/2010.04528v1.pdf

Where the authors show that fq_codel is feasible on the PISA platform...

but a direct comparison between the two papers is not possible. What I
don't understand about the above paper is how codel timestamps are
passed from ingress to egress.
