04ed4e984e AP: Only enable WPS for open and WPA/WPA2-Personal configuration
When wpa_supplicant AP mode is used, WPS was enabled by default
regardless of security mode. This is not desired for WEP, so change
the AP configuration to enable WPS only for open and WPA/WPA2-Personal
networks.

16476dd124 Fix P2P IE configuration for GO mode
Commit c2ff13c533 broke this with a
copy-paste typo that ended up adding the Probe Request P2P IE into the
Beacon frame (i.e., Beacon frame had two P2P IEs while Probe Response
had none).

update driver_ndis.c for all changes in that structure.

6f75536fc9 WPS: Send the credential when learning AP params in registrar role
When the supplicant acts as a registrar to learn the access point
parameters send the credentials to the wpa_cli interface after

Without this patch, after the 7th message you got the WPS-CRED-RECEIVED
notification without the credentials. This was because the cred_attr and
cred_attr_len were not filled in in the wps structure.
