Yes, it is logical because without multicast IPV6 cannot
work correctly.

But from another perspective (I assume these bridged Xen devices use
ARPHRD_ETHER, do they?) a device with ARPHRD_ETHER and cleared
IFF_MULTICAST flag seems potentially problematic.  How many other
things break over such a device?
