void mac_process_beacon_frame | ( | buffer_t * | beacon | ) |
Processes received beacon frame.
This function processes a received beacon frame. When the system is scanning it records PAN descriptor information contained in the beacon. These PAN descriptors will be reported to the next higher layer via MLME_SCAN.confirm. Also this routine constructs the MLME_BEACON_NOTIFY.indication. Additionally when a device is synced with the coordinator, it tracks beacon frames, checks whether the coordinator does have pending data and will initiate the transmission of a data request frame. The routine uses global "parse_data" structure. The PAN descriptors are stored in the mlme_scan_conf_t structure.
