[PATCH net-next v2 3/5] net: phy: Add pluming for ethtool_{get,set}_rxnfc

From: Florian Fainelli
Date: Thu Oct 26 2023 - 18:55:51 EST


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.
