You are not supposed to trust the device name, since probing can
happen in parallel, on different buses. udev should have rules to name
the interfaces based on the MAC address. On my Debian system i have:
/etc/udev/rules.d/70-persistent-net.rules
So what is important is that the MAC addresses are assigned correctly
to the device. And DT does that based on MMIO address, so should be
reliable, independent of probe order.
