official lede from sinovoip still uses 4.9, but there is imho also a dsa-driver (backported from 4.1x afair),
there is openwrt with 4.14 which includes Patches for bpi-r2 (where i've got my Patches for second gmac).
 
if you have a dsa-driver (you see interfaces wan,lan0-lan3) you cannot work on eth0/eth1 (these are only the ethernet-connections between switch [mt7530] and SOC/Main-CPU [mt7623]), only bring them up...ip-config has to be done on dsa-interfaces.

i've got second gmac working in 4.19 and with some advice from a DSA-Maintainer, i changed it (back) to mdio_device (johns patch uses platform_device).

The main porting of second gmac was done by john crispin. There was only a small mistake which we fixed (both cpu-ports need to use same mode).
 
I tried to port it to 4.19,but currently i can't get it working (eth1 is visible but dsa-ports got lost) so i stuck here without any help. I've contacted John,but he tells me he is currently busy and has not the time he need to help me.

Have contacted dave miller as maintainer of network-part,but got no response yet

Hi,
 
i changed Uart (Uart2=>ttyS0) and MMC (SD=0,emmc=1) from mainline to make my kernels compatible with official images (defined my images same way).
 
i see some definitions...maybe they can be used to define which uart is used for debug-uart without changing the order in dts(i)
aliases { serial2 = &uart2; }; chosen { stdout-path = "serial2:115200n8"; }; btw. 2nd gmac, hdmi, poweroff and some other stuff is working now in (my) 4.14...hnat is ported, but i don't know if it is working due to a "strange" test (cpu-interrupts increasing)
