Hmm.. Can you please show the wpa_supplicant command line that is used
here and describe how that network block gets configured for the
p2p-dev-wlan0 "interface"? I would have expected that there would never
be a configuration with an enabled network block being passed for the
P2P management interface.. Internally, wpa_supplicant should not add
such for P2P groups, but I don't think there is any filtering on
configuration if something is externally trying to make wpa_supplicant
use that management interface for a station mode connection.
