Subject: [PATCH net-next] net: phy: let genphy_c45_read_abilities also check aneg capability
Date: Fri, 22 Feb 2019 08:23:04 +0100	[thread overview]
Message-ID: <a798f789-94a9-f1ac-1cba-276a2c517089@gmail.com> (raw)

When using genphy_c45_read_abilities() as get_features callback we
also have to set the autoneg capability in phydev->supported.
