Ethernet not working on Orange Pi One Plus (H6)

[retpolanne]

Hello! I wanted to use this issue to document what we need to enable Ethernet on the Orange Pi One Plus.

It seems that the Orange Pi One Plus doesn't have upstream support for ethernet:

I made a hacky patch (attached to this issue) and added it to sunxi bbappends.
0003-sunxi-H6-Enable-Ethernet-on-Orange-Pi-One-Plus.patch

=> dhcp
sun8i_emac_eth_start: Timeout

Added the CONFIG_RTL8211E_PINE64_GIGABIT_FIX from [3] and started seeing also this error:

=> dhcp
mdio_register: non unique device name 'ethernet@5020000'
sun8i_emac_eth_start: Timeout

The thread [4] reports the same error.

ok nice, can you post PR with this patch to this meta layer please? Thanks.

[retpolanne]

Sure! Will do. I'll be out the whole day but I should send it today or tomorrow Brazil time
