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.
