The cpsw holds separate mcast entires for vlan entries. At this moment

As result mcast for vlans doesn't work. It can be fixed by adding same
mcast entries for every created vlan, but this patchseries uses more
sophisticated way and allows to create mcast entries only for vlans
that really require it. Generic functions from this series can be
reused for fixing vlan and macvlan unicast.

I assume this is first of all for dual_mac mode.
Mainly yes, but affects on switch mode also (and single port) adding
appropriate mcast entries.
