User can configure the below beacon tx mode
1. 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.

what happened to 0?
now we're back to the issue that I originally reported that if the
