Since P2P is dependent over wifi technology, it will get its technology
registered by this one if only one of the interface supports it.
Following the same logic, once an interface is removed the wifi
technology will check if the P2P technology is still supported by - at
least one of - the other interfaces, if any. If not, the P2P technology
will be then unregistered.
