We observe some packets are discarded in ieee80211_rx_handlers_result function for WCN7850. This is because the way to get multicast/broadcast indicator with RX_MSDU_END_INFO5_DA_IS_MCBC & info5 is incorrect. It should use RX_MSDU_END_INFO13_MCAST_BCAST & info13 to get multicast/broadcast indicator.
