Yeah, it does, at least if you assume that the capabilities can
actually change. We assume they don't though, hostapd/wpa_s for
example will never re-query them after startup.

Restarting supplicant, even if it came to that, might be less
of an issue than having to re-create the vdev to have it grab
proper new settings from the wiphy...

Well, it would be easy enough to make a method that updated an
vdev/sdata->vht from wiphy, so could just call that as needed (ie,
when certain things set or are changed by wiphy).

Yeah, I think we'll just have to deal with this when it comes along.
This multi-antenna-sharing case (unfortunately I forgot who was talking
about it) is the only thing that comes to mind where we really may have
to deal with this.
