You need to add #address-cells and #size-cells properties, otherwise "make 
dtbs_check W=1" generates warnings.

Additionally, it's not a good idea to change order of ethernet nodes. It can 
affect mac address assigning procedure in bootloader.

There is no eth1addr in uboot, so this doesn't affect the mac address.
The network order in the kernel is eth0(emac) / eth1(rtl8153) / wlan0,
so I think it would be better to change it this way.

Thanks,
Chukun

Really? I don't have a board at hand to double check, but the code I read
here says otherwise:
https://source.denx.de/u-boot/u-boot/-/blob/master/board/sunxi/board.c#L791-813
There it checks for up to four ethernet aliases and assigns MAC addresses
to them, using the index in the lowest byte.
So this would change the MAC address of the WiFi adapter.

Am I missing something?

> The network order in the kernel is eth0(emac) / eth1(rtl8153) / wlan0,

Regardless of the fact that you shouldn't rely on indexes in device names,
wouldn't that be that same, regardless of the order of USB and WiFi?

Andre

I'm very sorry for this, the rtl8189etv driver assigns the correct
mac address to wlan0, so I didn't observe the mac address change.
Sorry for my misunderstanding.
