[ Upstream commit 06095f34f8a0a2c4c83a19514c272699edd5f80b ]
Now CPSW ALE will set/clean Host port bit in Unregistered Multicast Flood Mask (UNREG_MCAST_FLOOD_MASK) for every VLAN without checking if this port belongs to VLAN or not when ALLMULTI mode flag is set for nedev. This is working in non dual_mac mode, but in dual_mac - it causes enabling/disabling ALLMULTI flag for both ports.
Hence fix it by adding additional parameter to cpsw_ale_set_allmulti() to specify ALE port number for which ALLMULTI has to be enabled and check if port belongs to VLAN before modifying UNREG_MCAST_FLOOD_MASK.
