Could we simply make a pull-request with the modification presented above here : https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi#L508 ?
If yes then, does setting the "allwinner,tx-delay-ps = <500>;" break the network on the sopine module when in the baseboard instead of the clusterboard (I only own the clusterboard) ?
If not then would making such a pull request not correct the armbian nightly build issue ? I have no idea where the original sun50i-a64-sopine-baseboard.dts file comes from if not the one linked above.
EDIT: I have dug a bit into the automated nightly build and it seems the kernel sources comes from : https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree/
So making a pull-request in github should be mirrored here https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree/arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi?h=linux-4.16.y#n508
But would not we need to do the pull request in every kernel version branch that needs to be patched ? (4.13.* and 4.14.* ?)
So there is actually a simpler patch but it's only works due to a coincidence that was fixed in Armbian.
This patch makes it so that all you need to set is rgmii-txid in the sopine dtb file(that's what I ended up changing after playing with a bunch of values for the manual delays)
So all of these are actually related to a packet loss issue on pine64(not sopine's) and some magic numbers they got from realtek. It coincidentally seems to solve issues with clusterboard, based on experimentation.
