====================
mlxsw: Adding layer 2 multicast

Elad says:

This patchset add Linux hardware reflection for L2 multicast offload and add
MC support in mlxsw. For every bridge MDB entry insertion, either by IGMP
snooping or by static insertion/removal, a switchdev ops is been called.
In mlxsw, a new multicast group (MID) is been created and ports are assigned.
When all ports are removed, the multicast group is been deleted.
