Fix REAUTHENTICATE command after PMKSA caching
The current PMKSA cache entry needs to be clear to allow EAPOL
reauthentication to be started in case this association used PMKSA
caching.
- Remove old WPS_OOB NCF
- WPS: Add preliminary NFC connection handover support for Enrollee
- WPS: Reenable the networks disabled during wpa_wpas_reassoc
- P2P: Avoid multi-channel scans when they are not needed
- P2P: Allow discoverable interval for p2p_find to be configured
- P2P: Allow all channels with multi-channel concurrency
- Bonjour changes
- Remove disassociate
- HS 2.0 changes
- Add preliminary support for using SQLite for eap_user database
- Add SAE support
- Add disallow_aps parameter to disallow BSSIDs/SSIDs
