# 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
# ----- -----------
# 0 - reserved, see section 7
# 1 server assignment
# 2 Diffie-Hellman exchange
# 3 GSS-API negotiation
# 4 resolver assignment
# 5 key deletion
# 6-65534 - available, see section 7
