  Ethernet MAC drivers supporting Wake-on-LAN using programmable filters
(WAKE_FILTER) typically configure such programmable filters using the
ethtool::set_rxnfc API and with a sepcial RX_CLS_FLOW_WAKE to indicate
the filter is also wake-up capable.

In order to offer the same functionality for capable Ethernet PHY
drivers, wire-up the ethtool::{get,set}_rxnfc APIs within the PHY
library.
