David or Jakub will handle the backport to stable. You should however set the subject to [PATCH net 1/2] and base the patches on the net tree, not net-next. Andrew

Enable GSWIP_MII_CFG_EN also for internal PHYs to make traffic flow. Without this the PHY link is detected properly and ethtool statistics for TX are increasing but there's no RX traffic coming in.
