11  * A mode 7 packet is used exchanging data between an NTP server
12  * and a client for purposes other than time synchronization, e.g.
13  * monitoring, statistics gathering and configuration.  A mode 7
14  * packet has the following format:
15  *
16  *    0			  1		      2			  3

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