[PATCH] arm64: dts: meson-g12a-x96-max: Add Gigabit Ethernet Support

From: Neil Armstrong
Date: Mon May 20 2019 - 09:46:07 EST


Enable the network interface of the X96 Mac using an external
Realtek RTL8211F gigabit PHY, needing the same broken-eee properties
as the previous Amlogic SoC generations.
