You are taking both positions at once - that this is *just* a 'bump on the wire' and everything is done via ethernet packets, and also that there is a special internal bus that nothing needs to know about. It is hard to be both ways, if it is ethernet packets there there are ways to create those packets outside the driver's control and security is a big question.
