Hmm...this is interesting. If we assume that the unicast, multicast and
broadcast types are all referring to IPv4, then unicast should probably
be very unreliable. On an Ethernet network, if the computer has been
sleeping long enough, it will become unreachable except by Ethernet
broadcast frames. Therefore, any attempts to do unicast waking will
fail when the sender is unable to find the relevant neighbour by ARP.
