That's not how IEEE 802.11 IBSS works. If you are trying to build some
kind of non-standard "ad-hoc network" using 802.11 to some extent, you
might be able to do something like this, but please note that this will
likely require custom changes in all the participating devices. I have
no interest in supporting that in wpa_supplicant (or cfg80211 for that
matter), so this would likely end up being a proprietary design for the
specific devices. In general, I'd assume there would be better ways of
doing whatever this is trying to achieve.
