         From the RFC:
         The NETWORK_BYTE_ORDER bit applies to all multi-byte integer
         values in the entire AgentX packet, including the remaining
         header fields.  If set, then network byte order (most
         significant byte first; "big endian") is used.  If not set,
         then least significant byte first ("little endian") is used.
