This is a note to let you know that I've just added the patch titled net: phy: meson-gxl: use MMD access dummy stubs for GXL, internal PHY to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: net-phy-meson-gxl-use-mmd-access-dummy-stubs-for-gxl.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit a0a8eb2205d6d86dfbcbe01ec85a3966c859ea0b Author: Heiner Kallweit <hkallweit1@xxxxxxxxx> Date: Thu Feb 2 21:45:36 2023 +0100 net: phy: meson-gxl: use MMD access dummy stubs for GXL, internal PHY [ Upstream commit 69ff53e4a4c9498eeed7d1441f68a1481dc69251 ] Jerome provided the information that also the GXL internal PHY doesn't support MMD register access and EEE. MMD reads return 0xffff, what results in e.g. completely wrong ethtool --show-eee output. Therefore use the MMD dummy stubs.
