13  * A mode 7 packet is used exchanging data between an NTP server
14  * and a client for purposes other than time synchronization, e.g.
15  * monitoring, statistics gathering and configuration.  A mode 7
16  * packet has the following format:
17  *

38  * where the fields are (note that the client sends requests, the server
39  * responses):
40  *
41  * Response Bit:  This packet is a response (if clear, packet is a request).
42  *
43  * More Bit:	Set for all packets but the last in a response which
44  *		requires more than one packet.
45  *
46  * Version Number: 2 for current version
47  *
48  * Mode:	Always 7
49  *
50  * Authenticated bit: If set, this packet is authenticated.
51  *
52  * Sequence number: For a multipacket response, contains the sequence
53  *		number of this packet.  0 is the first in the sequence,
54  *		127 (or less) is the last.  The More Bit must be set in
55  *		all packets but the last.
56  *
57  * Implementation number: The number of the implementation this request code
58  *		is defined by.  An implementation number of zero is used
59  *		for requst codes/data formats which all implementations
60  *		agree on.  Implementation number 255 is reserved (for
61  *		extensions, in case we run out).
62  *
63  * Request code: An implementation-specific code which specifies the
64  *		operation to be (which has been) performed and/or the
65  *		format and semantics of the data included in the packet.
66  *
67  * Err:		Must be 0 for a request.  For a response, holds an error
68  *		code relating to the request.  If nonzero, the operation
69  *		requested wasn't performed.
70  *
71  *		0 - no error
72  *		1 - incompatible implementation number
73  *		2 - unimplemented request code
74  *		3 - format error (wrong data items, data size, packet size etc.)
75  *		4 - no data available (e.g. request for details on unknown peer)
76  *		5-6 I don't know
77  *		7 - authentication failure (i.e. permission denied)
78  *
79  * Number of data items: number of data items in packet.  0 to 500
80  *
81  * MBZ:		A reserved data field, must be zero in requests and responses.
82  *
83  * Size of data item: size of each data item in packet.  0 to 500
84  *
85  * Data:	Variable sized area containing request/response data.  For
86  *		requests and responses the size in octets must be greater
87  *		than or equal to the product of the number of data items
88  *		and the size of a data item.  For requests the data area
89  *		must be exactly 40 octets in length.  For responses the
90  *		data area may be any length between 0 and 500 octets
91  *		inclusive.
92  *
93  * Message Authentication Code: Same as NTP spec, in definition and function.
94  *		May optionally be included in requests which require
95  *		authentication, is never included in responses.
96  *
97  * The version number, mode and keyid have the same function and are
98  * in the same location as a standard NTP packet.  The request packet
99  * is the same size as a standard NTP packet to ease receive buffer
100  * management, and to allow the same encryption procedure to be used
101  * both on mode 7 and standard NTP packets.  The mac is included when
102  * it is required that a request be authenticated, the keyid should be
103  * zero in requests in which the mac is not included.
104  *
105  * The data format depends on the implementation number/request code pair
106  * and whether the packet is a request or a response.  The only requirement
107  * is that data items start in the octet immediately following the size
108  * word and that data items be concatenated without padding between (i.e.
109  * if the data area is larger than data_items*size, all padding is at
110  * the end).  Padding is ignored, other than for encryption purposes.
111  * Implementations using encryption might want to include a time stamp
112  * or other data in the request packet padding.  The key used for requests
113  * is implementation defined, but key 15 is suggested as a default.
