The `phy_tunable_id` has been named `ETHTOOL_PHY_EDPD` since it looks like this feature is common across other PHYs (like EEE), and defining `ETHTOOL_PHY_ENERGY_DETECT_POWER_DOWN` seems too long. The way EDPD works, is that the RX block is put to a lower power mode, except for link-pulse detection circuits. The TX block is also put to low power mode, but the PHY wakes-up periodically to send link pulses, to avoid lock-ups in case the other side is also in EDPD mode. Currently, there are 2 PHY drivers that look like they could use this new PHY tunable feature: the `adin` && `micrel` PHYs. This series updates only the `adin` PHY driver to support this new feature, as this chip has been tested. A change for `micrel` can be proposed after a discussion of the PHY-tunable API is resolved. ==================== Signed-off-by: David S. Miller --- 1b8da10370d4accc33068dea48151ac957fa4dc5
