Comment(by ashish):

 I would like to add a few things here.
 Driver does store beacon interval and also whether beacon is enabled or
 not. All network start (adhoc start/infra join) commands pass this stored
 beacon interval to the firmware and firmware updates mesh beacon frequency
 based on the received value from these commands.
 Also, when we get beacon interval with iwpriv call it returns already
 stored beacon interval and does not fetch beacon information from the
 firmware.
 However, when we set beacon, it modifies driver's stored beacon interval
 and also pass down new beacon interval to the firmware.
 By default, beacons are enbaled with interval of 100ms, so I suspect that
 when NM is running probably it's trying to pass down ad-hoc
 start/join/infra join command with deafult beacon interval of 100ms to the
 firmware.
 driver log with
 echo 0x126000 > /sys/module/libertas/parameters/libertas_debug
 can shed more light on this.
 A sniffer capture may also help.
