Currently, RX is_mcbc bit is set for packest send from client as destination address (DA) is multicast/broadcast address, but packets are actually unicast as receiver address (RA) is not multicast address. Hence, packets are not handled properly due to this is_mcbc bit. Therefore, reset the is_mcbc bit if interface type is AP.
