The cpsw holds separate mcast entires for vlan entries. At this moment
driver adds only not vlan mcast addresses, omitting vlan/mcast entries.
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.
Simple example of ALE table before and after this series, having same
mcast entries as for vlan 100 as for real device (reserved vlan 2),
and one mcast address only for vlan 100 - 01:1b:19:00:00:00.

Here mcast entry (ptpl2), is added only for vlan 100
as it should be.
Based on net-next/master
Thank you.

For patch 1 - I'm not sure, so it'd good to get more comments.
