What's wrong with:
Ethernet V. 1
Ethernet V. 2
Ethernet V. 3
Ethernet V. 4
etc...
or would that be too simple?

The Advanced Research ProjectS Agency invented TCP/IP. But they didn't
invent Ethernet and I don't think the term arpa should be used to refer to
an Ethernet frame type. I know why Cisco uses the term. There's an old RFC
that talks about encapsulating IP in Ethernet frames. RFC implies ARPA.
But I think they should call the Ethernet frame type something that has to
do with the history of Ethernet, not the history of TCP/IP, especially
since the frame type can be used for other protocols besides IP. How about:
DIX
Ethernet2
EthernetII
EtherType
or something! ;-)
