If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 64cd92d5e8180c2ded3fdea76862de6f596ae2c9 Mon Sep 17 00:00:00 2001 From: Andrew Lunn <andrew@xxxxxxx> Date: Sun, 24 Oct 2021 21:48:03 +0200 Subject: phy: phy_ethtool_ksettings_set: Move after phy_start_aneg From: Andrew Lunn <andrew@xxxxxxx> commit 64cd92d5e8180c2ded3fdea76862de6f596ae2c9 upstream. This allows it to make use of a helper which assume the PHY is already locked.
