From b3a42e3a78ce0599c700a8c89befc67a35d54c31 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Wed, 28 Aug 2019 22:29:05 +0200 Subject: r8169: add support for EEE on RTL8125 This adds EEE support for RTL8125 based on the vendor driver. Supported is EEE for 100Mbps and 1Gbps. Realtek recommended to not yet enable EEE for 2.5Gbps due to potential compatibility issues. Also ethtool doesn't support yet controlling EEE for 2.5Gbps and 5Gbps. Signed-off-by: Heiner Kallweit Signed-off-by: David S.
