IPv6 Over Nothing

A perspective on the function of the network layer is that it abstracts away the differences between the various underlying link layer frame and addressing formats, unifying them into a common protocol data unit format and addressing scheme, namely the IPv4 or IPv6 protocols, and hiding those details from the upper transport layer protocols. As IPv6 is expected to become the dominant network layer protocol, and Ethernet has become the dominant link layer protocol, this memo proposes eliminating the overhead of the abstraction of Ethernet by IPv6 and using IPv6 directly as both the link layer and network layer protocol.
