+Credential generation and configuration changes
+By default, hostapd generates credentials for Enrollees and processing
+AP configuration updates internally. However, it is possible to
+control these operations from external programs, if desired.
+The internal credential generation can be disabled with
+skip_cred_build=1 option in the configuration. extra_cred option will
+then need to be used to provide pre-configured Credential attribute(s)
+for hostapd to use. The exact data from this binary file will be sent,
+i.e., it will have to include valid WPS attributes. extra_cred can
+also be used to add additional networks if the Registrar is used to
+configure credentials for multiple networks.
+Processing of received configuration updates can be disabled with
+wps_cred_processing=1 option. When this is used, an external program
+is responsible for creating hostapd configuration files and processing
+configuration updates based on messages received from hostapd over
+control interface. This will also include the initial configuration on
+first successful registration if the AP is initially set in
+unconfigured state.
+Following control interface messages are sent out for external programs:
+WPS-REG-SUCCESS <Enrollee MAC address <UUID-E>
+For example:
+<2>WPS-REG-SUCCESS 02:66:a0:ee:17:27 2b7093f1-d6fb-5108-adbb-bea66bb87333
+This can be used to tricker change from unconfigured to configured
+state (random configuration based on the first successful WPS
+registration). In addition, this can be used to update AP UI about the
+status of WPS registration progress.
