Any hope for 802.11ac on an Atheros chip?

I recently got a laptop, and picked up an Atheros QCA6174 2x2 802.11ac
card for it. But after putting it in. FreeBSD-(13 && 13.1) doesn't even
know it's there. I was sure that they were supported, as it was reported
to be "close/almost finished" in the July-September 2020 Quarterly report[1]
as well as a report by Adrian that "We know whats missing"[2] somewhat
later on the mailing list.
So where can I find it? :-)

Thank you for all your time, and consideration.
