No. I have been too busy with Intel drivers instead.
Currently I am working on a new driver based on iwm(4) for newer
Intel hardware (ax200).
I don't want to work on more than one driver at a time.

It would be great if the industry stopped putting out new chipsets
for a few years so we can manage to catch up.

In this case it can be ported from Linux. However, that is a lot more
involved than mere copy/paste; it essentially requires going through
the entire driver and port the neccessary parts of the code incrementally.
Check Patrick's talk from EuroBSDcon 2019 about bwfm; this is a similar
situation.

The 11n support net80211 and iwm/iwn needs to be completed before
working on 11ac makes any sense. What is lacking in particular on
the way towards 11ac is 40 MHz channel support. Also, Tx aggregation
support needs to be added to iwm(4), as was done in iwn(4) some time ago.
