This will add "01:00:5e:00:00:25" to the device multicast address filter,
which will mean the host will receive the packet. But because it doesn't
join the group at the IP level, it'll be dropped and the ping won't be
answered (it isn't for a local address).

If you want the machine to answer, you need to join the group, which
will conveniently add the hardware multicast address automatically. :-)
