This is for a bit of an edge case related to planned use by Incus OS. Basically we want to be able to have an Incus cluster with an internal IPv6 network which is connected through multicast VXLAN. In that scenario each individual server will be acting as a router emitting RAs. For proper operation we need each server to have its own MAC address and we need a way to avoid duplicate host addresses. For that reason, we're now making two changes: - Require a machine specific MAC address when tunnels are used - Support automatically deriving (EUI64) a local IPv6 address when provided with an address-less /64 IPv6 subnet.
