I don't really see why you couldn't change that though? There's no
fundamental reason you need to load the firmware before registering with
mac80211?

And fundamentally, I'm not even sure how you are achieving a change of
the ops - you're meant to point those to a *const* ops, so you need two
versions of the ops, one with and one without chanctx, and point to the
correct one at allocation ...
