The problem is most of the time if you have multiple NICs, they use the
same chipset.  That means the ethX order is determined by the device
driver, not by the module load order, and the device drivers have no
standardized way of indicating which physical interface is "first".

So...either something has to talk to the kernel the way modprobe, udev,
etc. manage to do, or a different approach is needed (perhaps using MAC
addresses or logical names to identify the interfaces instead of ethX).
