Enable Wake On Lan (WOL) support, if available.
WOL is a facility whereby a machine in a low power state may be woken
in response to a received packet.
There are three types of packets that may wake a system:
ucast (directed solely to the machine's mac address),
mcast (directed to a broadcast or multicast address),
or
magic (unicast or multicast frames with a ``magic contents'').
Not all devices support WOL, those that do indicate the mechanisms
they support in their capabilities.
.Cm wol
