Yes, I know that. However, the packets are being encapsulated in some
way. They may be encapsulating the IP packets directly or they may be
encapsulating the ethernet packets as PPP does. Either way there is an
opportunity for problems similar to those that have developed with
PPPoE because encapsulization always involves adding headers. The
packets are being encapsulated for the WiFi too, of course.
