WLAN beacons are identical from one beacon to the other, in most cases, other than the timestamp (TSF) and the Traffic Indication Map (TIM) information.
The TSF and the TIM are handled by the firmware (for real-time purposes). The WiLink8 driver (and supplicant) always receives one (first) beacon; the others are configurable. The host can configure to the firmware which IEs are relevant and the firmware sends the driver only beacons with the configured IEs.
The host can configure for each relevant IE whether the Transfer, when there is a change in the IE's content, or Relevant IE appears in the beacon. For the latter, the firmware saves the last beacon in its DB, and compares the new beacon with the beacon from the DB. If there is a match, the entire beacon will be sent to the host. Each IE that is not configured is handled as non-relevant and ignored.
Configure the IEs with TI wlconf file as shown in Table 15.
