637		-
638		-ChirpStack has support for creating multicast-groups to which devices can be assigned. When enqueueing a downlink payload for a multicast-group, ChirpStack will analyze which gateways must be used for broadcasting to cover the complete multicast-group. This means that potentially, a single multicast downlink payload will be emitted multiple times.
639		-
640		-Multicast can be used for the following device-classes:
641		-
642		-* Class-B
643		-* Class-C
