Ethernet interface not going up again (with "ifconfig eth0 up", on Rpi3)

Hi @chrischabot,

thanks a lot for the information.
The documentation is very helpful.

Is there an overview somewhere of what Resin is doing (or not doing) to maintain network connections?
I am trying to get a sense about which points of failiure I will have to take into account in my own code and what already safely works out of the box.

Greetings,
Chris
