if you are getting a pure codel result of 160ms, that means the

with a fq_codel *qdisc* doing the work on top of huge buffers,
Yes. The 160ms is with fq_codel qdisc with ath10k doing DQL at 6mbps.
Without DQL ath10k would clog up all tx slots (1424 of them) with
frames. At 6mbps you typically want/need a handful (5-10) of frames to
be queued.
Have you actually verified you can use all tx slots? The way the
firmware uses it's tx buffers I think you may not be able to actually
do that...and in practice, you will get a lot fewer usable tx-buffers
than configured....
