To flush the vid + mc entries from ALE, which is required when a VLAN interface is removed, driver needs to call cpsw_ale_flush_multicast() with ALE_PORT_HOST for port mask as these entries are added only for host port. Without this, these entries remain in the ALE table even after removing the VLAN interface. cpsw_ale_flush_multicast() calls cpsw_ale_flush_mcast which expects a port mask to do the job.
