Staggered mode and 2. Burst mode while bring-up the AP or MESH. Beacons can be sent out in burst(continuously in a single shot one after another) or staggered (equally spread out over beacon interval) mode. Set the beacon_tx_mode as 1 for Staggered mode and 2 for burst mode. Hence, added the support in the nl80211/cfg80211 layer to honour the beacon tx mode configuration and pass this value to the driver.
