this line could be interesting but i dont know what does it mean exactly (or why is it happening):
dwmac-sun8i 5020000.ethernet eth0: stmmac_dvr_remove: removing driver
so I looked it up and found a similar problem where this question came up:
the first time the "extension board" was connected the other way around .. could this have caused a hardware problem? at startup, the LED of the ethernet port lights up for a moment, but then it doesn't light up even once. unfortunately, I don't have another device, so I can't find out if it's really a hardware error. I hope it's just some kind of bad system configuration
