Comment # 4 on bug 1205639 from Freek de Kruijf

I also needed to change eth0 in the firewalld configuration, so a better
solution is to enter the following in
/etc/udev/rules.d/70-persistent-net.rules:

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="dwmac-sun8i",
ATTR{dev_id}=="0x0",ATTR{type}=="1", ATTR{address}=="02:ba:f7:39:24:a4",NAM
E="eth0"

all on one line.
This brings the name back to eth0, where items, DRIVERS and ATTR{address} are
copied from:
