# Constants for the mode field - from RFC 2930:
    # 2.5 The Mode Field
    #
    #    The mode field specifies the general scheme for key agreement or
    #    the purpose of the TKEY DNS message.  Servers and resolvers
    #    supporting this specification MUST implement the Diffie-Hellman key
    #    agreement mode and the key deletion mode for queries.  All other
    #    modes are OPTIONAL.  A server supporting TKEY that receives a TKEY
    #    request with a mode it does not support returns the BADMODE error.
    #    The following values of the Mode octet are defined, available, or
    #    reserved:
    #
    #          Value    Description
    #          -----    -----------
