wifi: ath12k: using msdu end descriptor to check for rx multicast packets
[ Upstream commit cb7433cc5cd4d07175dbc41f5a19966e9fae48be ]
Currently, the RX multicast broadcast packet check is performed using
bit 15 from the info6 field of the MPDU start descriptor. This check
can also be done using bit 9 from the info5 field of the MSDU end
descriptor. However, in some scenarios multicast bit is not set when
fetched from MPDU start descriptor.
Therefore, checking the RX multicast broadcast packet from the MSDU
end descriptor is more reliable as it is per MSDU.
