+Subject: [PATCH] net phy: Check for aneg completion before setting state to
+ PHY_RUNNING
+
+phy_state_machine should check whether auto-negotiatin is completed
+before changing phydev->state from PHY_NOLINK to PHY_RUNNING. If
+auto-negotiation is not completed phydev->state should be set to
+PHY_AN.
