Yeah, seems the support is back: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-September/530590.html
Just built full orangepi plus image using Igors marvellous build system selecting "next" kernel 4.13.3, pushed it onto the sd card and tadaa:
root@orangepiplus:~# uname -a
Linux orangepiplus 4.13.3-sunxi #1 SMP Sat Sep 23 16:37:58 CEST 2017 armv7l GNU/Linux
...
[Sat Sep 23 20:12:03 2017] dwmac-sun8i 1c30000.ethernet eth0: Link is Up - 1Gbps/Full - flow control rx/tx
Feels like I've been waiting years for this moment ... no 3.x kernel anymore on my orange pi Many thanx to all involved people who made this possible!
