+Subject: [PATCH] lan78xx: Move enabling of EEE into PHY init code
+
+Enable EEE mode as soon as possible after connecting to the PHY, and
+before phy_start. This avoids a second link negotiation, which speeds
+up booting and stops the interface failing to become ready.
+
+See: https://github.com/raspberrypi/linux/issues/2437
