   4 Subject: [PATCH v2] arm64: dts: allwinner: orangepi-zero-plus: fix PHY mode
   5
   6 Orange Pi Zero Plus uses a Realtek RTL8211E RGMII Gigabit PHY, but its
   7 currently set to plain RGMII mode meaning that it doesn't introduce
   8 delays.
   9
  10 With this setup, TX packets are completely lost and changing the mode to
  11 RGMII-ID so the PHY will add delays internally fixes the issue.
