Currently, adding any sort of IPv6 nwfilter rules is rather difficult. There

Also worth an example of what this will contain (such as

+ parsedMac.addr[0] ^= 2;
Oh, and forgot to mention, should this be |= instead of ^=, since by
default, libvirt assigns MAC addresses with bit 2 already set? My
understanding is that bit 2 is the locally-administered bit, and that
the V6LOCAL address always wants it set (^= only works if the MAC
address is not also locally administered, but libvirt's generated MAC
addresses of 52:54:00:xx:yy:zz fall foul of that)
For link-local addresses, you want to invert the bit, not ensure that
it's always set. This matches what linux is doing doing:
