Jouni Malinen fdb45355d4 WPS: Extend per-station PSK to support ER case as well
When wpa_psk_file is used instead of wpa_psk/wpa_passphrase, each WPS
Enrollee was given a unique PSK. This did not work for the
station-as-Registrar case where ER would learn the current AP settings
instead of enrolling itself (i.e., when using the AP PIN instead of
station PIN). That case can be covered with a similar design, so
generate a per-device PSK when building M7 as an AP in wpa_psk_file
configuration.
