That's not a requirement from our side but feel free to add that if you
want. Usually we do so that if the patch has "[PATCH wireless]" or
"[PATCH v6.6]" we queue the patch to wireless tree, otherwise it's
queued for wireless-next.

Yeah, we do work a bit different compared to net-next. For example,
wireless-next remains open during merge windows so you can submit
patches anytime. We have tried to document our practises in the wiki
link below in my signature.
