The example assumes that the master has radar detection capabilities and is able to evacuate its operating channel if needed (which must be followed by the device also evicting the WFD operation from this channel). The purpose of this patch was to allow the instantiation of a GO on channels marked as indoor/Concurrent GO assuming some conditions are met, ignoring the NO_IBSS and PASSIVE channels. I intend to implement to full restriction logic in the wpa_supplicant (based on the device type etc.), and also handle the actual indication that this channel can no longer be used, eviction and new channel selection in the wpa_supplicant. > > Furthermore, it is assumed, that if the conditions that allowed for > > the operation of the GO on such a channel change, it is the > > responsibility of user space to evacuate the GO from the channel. > > Do you have plans or changes to address this?
