PASN: Add support for PASN processing to wpa_supplicant Add PASN implementation to wpa_supplicant 1. Add functions to initialize and clear PASN data. 2. Add functions to construct PASN Authentication frames. 3. Add function to process PASN Authentication frame. 4. Add function to handle PASN frame TX status. 5. Implement the station side flow processing for PASN. The implementation is missing support for wrapped data and PMKSA establishment for base AKMs, and only supports PASN authentication or base AKM with PMKSA caching. The missing parts will be added in later patches. Signed-off-by: Ilan Peer <ilan.peer@intel.com>

PASN: Offload handshake for multiple peers from the driver This brings in the functionality to hold multiple peers and perform PASN authentication with each peer at a time and send the PASN response to the driver. PASN parameters such as AKMP and cipher suite are obtained from the BSS information of the cached scan results. Also add functionality to trigger deauthentication to the peer for which PASN request with action PASN_ACTION_DELETE_SECURE_RANGING_CONTEXT is received.

PASN: Add support for PASN processing to wpa_supplicant Add PASN implementation to wpa_supplicant 1. Add functions to initialize and clear PASN data. 2. Add functions to construct PASN Authentication frames. 3. Add function to process PASN Authentication frame. 4. Add function to handle PASN frame TX status. 5. Implement the station side flow processing for PASN. The implementation is missing support for wrapped data and PMKSA establishment for base AKMs, and only supports PASN authentication or base AKM with PMKSA caching. The missing parts will be added in later patches. Signed-off-by: Ilan Peer <ilan.peer@intel.com>

Add functions to construct PASN Authentication frames. 3. Add function to process PASN Authentication frame. 4. Add function to handle PASN frame TX status. 5. Implement the station side flow processing for PASN. The implementation is missing support for wrapped data and PMKSA establishment for base AKMs, and only supports PASN authentication or base AKM with PMKSA caching. The missing parts will be added in later patches. Signed-off-by: Ilan Peer <ilan.peer@intel.com>

Hence, initialize the context through init and deinit functions. Also use set and get functions to update the parameters. Signed-off-by: Jouni Malinen <quic_jouni@quicinc.com>
