In dual-emac mode the cpsw driver sends directed packets, that means that packets go to the directed port, but an ALE lookup is performed to determine untagged egress only. It means that on tx side no need to add port bit for ALE mcast entry mask, and basically ALE entry for port identification is needed only on rx side. So, add only host port in dual_emac mode as used directed transmission, and no need in one more port. For single port boards and switch mode all ports used, as usual, so no changes for them. Also it simplifies farther changes. In other words, mcast entries for dual-emac should behave exactly like unicast. It also can help avoid leaking packets between ports with same vlan on h/w level if ports could became members of same vid. So now, for instance, if mcast address 33:33:00:00:00:01 is added then entries in ALE table: vid = 1, addr = 33:33:00:00:00:01, port_mask = 0x1 vid = 2, addr = 33:33:00:00:00:01, port_mask = 0x1 Instead of: vid = 1, addr = 33:33:00:00:00:01, port_mask = 0x3 vid = 2, addr = 33:33:00:00:00:01, port_mask = 0x5 With the same considerations, set only host port for unregistered mcast for dual-emac mode in case of IFF_ALLMULTI is set, exactly like it's done in cpsw_ale_set_allmulti().
