description:
Summary: let wg interfaces carry multicast traffic
Once a wg interface is up and running, it is useful to be able to run
a routing protocol over it. Marking the interface multicast capable
enables this. (One must also use the wgconfig --allowed-ips option to
explicitly permit the group one needs, e.g. 224.0.0.5/32 for OSPF.)
