The network diagram is very simple. It is just:
VM <--* MR > PH
Where:
MR = Multicast Router
VM = Virtual Machine (connected by a Virtual Interface using the
'virtio_net' driver)
PH = Physical Host (connected by a physical Ethernet connection)
* = The interface where the packet orig

Currently, when forwarding a multicast packet originating from a
Virtual Interface on a Multicast Router to one of its Physical
Interfaces, ip_summed is set to a value of CHECKSUM_UNNECESSARY and
the UDP checksum is not calculated.
The checksum value of the forwarded packet is left as is and
there
