No, it is _defined_ and designed to be generic in rfc826 by Davit C Plummer.
The rfcs for specific media just define the protocol id numbers and address
lengths, which should be inserted. It was a quite ingenious piece of work,
foretelling any possible use.
Btw., the author was an old DECineer: he used symbolic names like
ARP$CODE for the fields of the packet and the variables of his

Ah, I didn't read that, but so I guessed from the code.

So I'm out of luck.
