How would a user know when to use the new ftm_responder_capab_only vs.
the old ftm_responder_capab configuration parameter? What happens if
ftp_responder_capab_only=1 is used and there is no userspace daemon to
process the operations? Is this something that could be handled
automatically? It would seem to be much more convenient to not add this
new configuration parameter at all and instead determine the FTM
responder location between the driver and that separate userspace daemon
automatically so that it does not matter whether hostapd/wpa_supplicant
requests the driver to process the requests.
