* A mode 7 packet is used exchanging data between an NTP server

* 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

*
* where the fields are (note that the client sends requests, the server
* responses):
*
* Response Bit: This packet is a response (if clear, packet is a request).
*
* More Bit: Set for all packets but the last in a response which
* requires more than one packet.
*
* Version Number: 2 for current version
*
* Mode: Always 7
*
* Authenticated bit: If set, this packet is authenticated.
*
* Sequence number: For a multipacket response, contains the sequence
* number of this packet. 0 is the first in the sequence,
* 127 (or less) is the last. The More Bit must be set in
* all packets but the last.
*
* Implementation number: The number of the implementation this request code
* is defined by. An implementation number of zero is used
* for requst codes/data formats which all implementations
* agree on. Implementation number 255 is reserved (for
* extensions, in case we run out).
*
* Request code: An implementation-specific code which specifies the
* operation to be (which has been) performed and/or the
* format and semantics of the data included in the packet.
*
* Err: Must be 0 for a request. For a response, holds an error
* code relating to the request. If nonzero, the operation
* requested wasn't performed.
*
* 0 - no error
* 1 - incompatible implementation number
* 2 - unimplemented request code
* 3 - format error (wrong data items, data size, packet size etc.)
* 4 - no data available (e.g. request for details on unknown peer)
* 5-6 I don't know
* 7 - authentication failure (i.e. permission denied)
*
* Number of data items: number of data items in packet. 0 to 500
*
* MBZ: A reserved data field, must be zero in requests and responses.
*
* Size of data item: size of each data item in packet. 0 to 500
*
* Data: Variable sized area containing request/response data. For
* requests and responses the size in octets must be greater
* than or equal to the product of the number of data items
* and the size of a data item. For requests the data area
* must be exactly 40 octets in length. For responses the
* data area may be any length between 0 and 500 octets
* inclusive.
*
* Message Authentication Code: Same as NTP spec, in definition and function.
* May optionally be included in requests which require
* authentication, is never included in responses.
*
* The version number, mode and keyid have the same function and are
* in the same location as a standard NTP packet. The request packet
* is the same size as a standard NTP packet to ease receive buffer
* management, and to allow the same encryption procedure to be used
* both on mode 7 and standard NTP packets. The mac is included when
* it is required that a request be authenticated, the keyid should be
* zero in requests in which the mac is not included.
*
* The data format depends on the implementation number/request code pair
* and whether the packet is a request or a response. The only requirement
* is that data items start in the octet immediately following the size
* word and that data items be concatenated without padding between (i.e.
* if the data area is larger than data_items*size, all padding is at
* the end). Padding is ignored, other than for encryption purposes.
* Implementations using encryption might want to include a time stamp
* or other data in the request packet padding. The key used for requests
* is implementation defined, but key 15 is suggested as a default.
