Add a new character 'f' which can be used to configure an Ethernet
controller to support Wake-on-LAN using filters programmed with the
ethtool::rxnfc and the special action -2 (wake-up filter). This is
useful in particular in the context of devices that must support wake-up
on more complex patterns such as multicast DNS packets.
