Merge branch 'mlxsw-traps' 

Jiri Pirko says:

====================
mlxsw: Traps enhancements

Ido says:

The first patch makes sure the driver marks packets that were trapped
in the router and might have already been flooded by the bridge, so that
the bridge driver won't flood them again. This isn't critical at this time
point, but will be when Neighbour Discovery traps are introduced as these
are multicast packets that are trapped in the router.

The second and third patches add new traps - for MLD and Router Alert
packets. The last patch takes advantage of that and floods IPv6
unregistered multicast packets only to mrouter ports instead of all ports.
