FYI - in some offline discussion last week Keith McCloghrie
observed that a 16 bit ar$pro space could be further subdivided in
a logical fashion to include the NPLID space. I'm posting this
to for contemplation by the WG (and to ensure Keith gets
public attribution for this neat idea).

The description of ar$pro would now read:

      0x0000 to 0x00FF  Protocols defined by the equivalent NPLIDs.
      0x0100 to 0x03FF  Reserved for future use by the IETF.
      0x0400 to 0x05FF  Designated for use by the ATM Forum.
      0x0600 to 0xFFFF  Protocols defined by the equivalent Ethertypes.

(based on the observations that valid Ethertypes are never smaller
than 0x600, and NPLIDs never larger than 0xFF.)

cheers,
