When running NetworkManager, NM will communicate with an already-running
wpa_supplicant, or it will ask D-Bus to spawn a supplicant for it.  And
then if you run a supplicant yourself, they will fight over the
interface and you may well see the "reason=3 locally_generated=1"
responses.  The solution here is to either manage the interface with
NetworkManager, or make NM ignore it and do it all yourself.
