+Subject: arm64: allwinner: a64: pine64: add missing ethernet0 alias
+
+The EMAC Ethernet controller was enabled, but an accompanying alias
+was not added. This results in unstable numbering if other Ethernet
+devices, such as a USB dongle, are present. Also, the bootloader uses
+the alias to assign a generated stable MAC address to the device node.
