Subject: [PATCH] rtlwifi: Uses addr1 instead DA to determine broadcast and multicast addr.
Git-commit: e7c528615e34a924c94d135e2f8e17bb9bf3b611
Patch-mainline: v4.14-rc1
References: FATE#326906
We should check addr1 to indicate a packet as broadcast or multicast
in tx desc. An obvious example, a STA transmit an *unicast* ARP packet
where addr1 and DA are the addresses of AP and broadcast respectively.
