    (01) BOOTREQUEST
    (02) BOOTREPLY
      

• htype_codes

  Imports all HTYPE (hardware address type) codes.

    (01) HTYPE_ETHER
    (06) HTYPE_IEEE802
    (08) HTYPE_FDDI
      

  Most common value is HTYPE_ETHER for "Ethernet".

• dhcp_message

  Import all DHCP Message codes.

    (01) DHCPDISCOVER
    (02) DHCPOFFER
    (03) DHCPREQUEST
    (04) DHCPDECLINE
    (05) DHCPACK
    (06) DHCPNAK
    (07) DHCPRELEASE
    (08) DHCPINFORM

    (10) DHCPLEASEQUERY
    (11) DHCPLEASEUNASSIGNED
    (12) DHCPLEASEUNKNOWN
    (13) DHCPLEASEACTIVE
      

  Nb. Previously Cisco used 13 for DHCPLEASEQUERY. If you need to decode or encode packets to communicate with such a system, you might simply use the integer rather than the constant - or use the updated constant and comment in your code appropriately.

• dho_codes

  Import all DHCP option codes.
