Coexistence need to send Null data to stop AP keeps TX packet to DUT
before DUT coexistence switch to Bluetooth time slot, or it will be an
interference to DUT BT and because DUT will not RX packet from AP
the packet retry may harmful to WL TP. Compare to v1 version, the newer
firmware report will also report Null TX data counter.
