        The following is extracted from rfc1010:

   The Address Resolution Protocol (ARP) specified in RFC 826 [64] has
   several parameters. The assigned values for these parameters are
   listed here.


      Operation Code (op)

         1 REQUEST
         2 REPLY

      Hardware Type (hrd)

         Type Description References
         ---- ----------- ----------
           1 Ethernet (10Mb) [JBP]
           2 Experimental Ethernet (3Mb) [JBP]
           3 Amateur Radio AX.25 [PXK]
           4 Proteon ProNET Token Ring [JBP]
           5 Chaos [GXP]
           6 IEEE 802 Networks [JBP]
           7 ARCNET [JBP]

      Protocol Type (pro)

         Use the same codes as listed in the section called "Ethernet
         Numbers of Interest" (all hardware types use this code set for
         the protocol type).
