If you are using ethernet cards to talk to each other, it _is_ ethernet.
The bits will be placed on the wire, the framing, CSMA/CD algorithm etc,
will all be done in accordance with the 802.3 spec. The physical wire
will be carrying the bits in 802.3 format, including the preamble,
starting frame delimiter, MAC destination addrress and MAC source address,
since the cards don't know how to use any other method of framing and
sending the data.
