37  *   Spinel is a host-controller protocol designed to enable
38  *   inter-operation over simple serial connections between general purpose
39  *   device operating systems (OS) host and network co-processors (NCP) for
40  *   the purpose of controlling and managing the NCP.

44  *   Frame Format
45  *
46  *   A frame is defined simply as the concatenation of
47  *
48  *   -  A header byte
49  *   -  A command (up to three bytes)
50  *   -  An optional command payload
51  *
52  *              +---------+--------+-----+-------------+
53  *              | Octets: |   1    | 1-3 |      n      |
54  *              +---------+--------+-----+-------------+

59  *
60  *   Header Format
61  *
62  *   The header byte is broken down as follows:
63  *
64  *                    0   1   2   3   4   5   6   7
65  *                  +---+---+---+---+---+---+---+---+
66  *                  |  FLG  |  IID  |      TID      |
67  *                  +---+---+---+---+---+---+---+---+
68  *
69  *
70  *   The flag field of the header byte ("FLG") is always set to the value
71  *   two (or "10" in binary).  Any frame received with these bits set to
72  *   any other value else MUST NOT be considered a Spinel frame.
73  *
74  *   This convention allows Spinel to be line compatible with BTLE HCI.
75  *   By defining the first two bit in this way we can disambiguate between
76  *   Spinel frames and HCI frames (which always start with either "0x01"
77  *   or "0x04") without any additional framing overhead.
78  *
79  *   The Interface Identifier (IID) is a number between 0 and 3, which
80  *   is associated by the OS with a specific NCP. This allows the protocol
81  *   to support multiple networks under same connection.
82  *
83  *   The least significant bits of the header represent the Transaction
84  *   Identifier (TID). The TID is used for correlating responses to the
85  *   commands which generated them.
86  *
87  *   When a command is sent from the host, any reply to that command sent
88  *   by the NCP will use the same value for the IID and TID.  When the host
89  *   receives a frame that matches the IID and TID of the command it sent, it
90  *   can easily recognize that frame as the actual response to that command.
91  *
92  *   The TID value of zero (0) is used for commands to which a correlated
93  *   response is not expected or needed, such as for unsolicited update
94  *   commands sent to the host from the NCP.

98  *   The command identifier is a 21-bit unsigned integer encoded in up to
99  *   three bytes using the packed unsigned integer format described below.
100  *   Depending on the semantics of the command in question, a payload MAY
101  *   be included in the frame.  The exact composition and length of the
102  *   payload is defined by the command identifier.

105  *
106  *   Data Packing
107  *
108  *   Data serialization for properties is performed using a light-weight
109  *   data packing format which was loosely inspired by D-Bus.  The format
110  *   of a serialization is defined by a specially formatted string.
111  *
112  *   This packing format is used for notational convenience.  While this
113  *   string-based data-type format has been designed so that the strings
114  *   may be directly used by a structured data parser, such a thing is not
115  *   required to implement Spinel.
116  *
117  *   Goals:
118  *
119  *   -  Be lightweight and favor direct representation of values.
120  *   -  Use an easily readable and memorable format string.
121  *   -  Support lists and structures.
122  *   -  Allow properties to be appended to structures while maintaining
123  *      backward compatibility.
124  *
125  *   Each primitive data-type has an ASCII character associated with it.
126  *   Structures can be represented as strings of these characters.  For
127  *   example:
128  *
129  *   -  "C": A single unsigned byte.
130  *   -  "C6U": A single unsigned byte, followed by a 128-bit IPv6 address,
131  *      followed by a zero-terminated UTF8 string.
132  *   -  "A(6)": An array of concatenated IPv6 addresses
133  *
134  *   In each case, the data is represented exactly as described.  For
135  *   example, an array of 10 IPv6 address is stored as 160 bytes.

177  *   Packed Unsigned Integer
178  *
179  *   For certain types of integers, such command or property identifiers,
180  *   usually have a value on the wire that is less than 127.  However, in
181  *   order to not preclude the use of values larger than 255, we would
182  *   need to add an extra byte.  Doing this would add an extra byte to the
183  *   majority of instances, which can add up in terms of bandwidth.
184  *
185  *   The packed unsigned integer format is based on the unsigned integer
186  *   format in EXI, except that we limit the maximum value to the
187  *   largest value that can be encoded into three bytes (2,097,151).
188  *
189  *   For all values less than 127, the packed form of the number is simply
190  *   a single byte which directly represents the number.  For values
191  *   larger than 127, the following process is used to encode the value:
192  *
193  *   1.  The unsigned integer is broken up into _n_ 7-bit chunks and
194  *       placed into _n_ octets, leaving the most significant bit of each
195  *       octet unused.
196  *   2.  Order the octets from least-significant to most-significant.
197  *       (Little-endian)
198  *   3.  Clear the most significant bit of the most significant octet.
199  *       Set the least significant bit on all other octets.
200  *
201  *   Where `n` is the smallest number of 7-bit chunks you can use to
202  *   represent the given value.
203  *
204  *   Take the value 1337, for example:
205  *
206  *                              1337 => 0x0539
207  *                                   => [39 0A]
208  *                                   => [B9 0A]
209  *
210  *   To decode the value, you collect the 7-bit chunks until you find an
211  *   octet with the most significant bit clear.

214  *
215  *   Data Blobs
216  *
217  *   There are two types for data blobs: "d" and "D".
218  *
219  *   -  "d" has the length of the data (in bytes) prepended to the data
220  *      (with the length encoded as type "S").  The size of the length
221  *      field is not included in the length.
222  *   -  "D" does not have a prepended length: the length of the data is
223  *      implied by the bytes remaining to be parsed.  It is an error for
224  *      "D" to not be the last type in a type in a type signature.
225  *
226  *   This dichotomy allows for more efficient encoding by eliminating
227  *   redundancy.  If the rest of the buffer is a data blob, encoding the
228  *   length would be redundant because we already know how many bytes are
229  *   in the rest of the buffer.
230  *
231  *   In some cases we use "d" even if it is the last field in a type
232  *   signature.  We do this to allow for us to be able to append
233  *   additional fields to the type signature if necessary in the future.
234  *   This is usually the case with embedded structs, like in the scan
235  *   results.
236  *
237  *   For example, let's say we have a buffer that is encoded with the
238  *   datatype signature of "CLLD".  In this case, it is pretty easy to
239  *   tell where the start and end of the data blob is: the start is 9
240  *   bytes from the start of the buffer, and its length is the length of
241  *   the buffer minus 9. (9 is the number of bytes taken up by a byte and
242  *   two longs)
243  *
244  *   The datatype signature "CLLDU" is illegal because we can't determine
245  *   where the last field (a zero-terminated UTF8 string) starts.  But the
246  *   datatype "CLLdU" is legal, because the parser can determine the
247  *   exact length of the data blob-- allowing it to know where the start
248  *   of the next field would be.

251  *
252  *   Structured Data
253  *
254  *   The structure data type ("t(...)") is a way of bundling together
255  *   several fields into a single structure.  It can be thought of as a
256  *   "d" type except that instead of being opaque, the fields in the
257  *   content are known.  This is useful for things like scan results where
258  *   you have substructures which are defined by different layers.
259  *
260  *   For example, consider the type signature "Lt(ES)t(6C)".  In this
261  *   hypothetical case, the first struct is defined by the MAC layer, and
262  *   the second struct is defined by the PHY layer.  Because of the use of
263  *   structures, we know exactly what part comes from that layer.
264  *   Additionally, we can add fields to each structure without introducing
265  *   backward compatibility problems: Data encoded as "Lt(ESU)t(6C)"
266  *   (Notice the extra "U") will decode just fine as "Lt(ES)t(6C)".
267  *   Additionally, if we don't care about the MAC layer and only care
268  *   about the network layer, we could parse as "Lt()t(6C)".
269  *
270  *   Note that data encoded as "Lt(ES)t(6C)" will also parse as "Ldd",
271  *   with the structures from both layers now being opaque data blobs.

274  *
275  *   Arrays
276  *
277  *   An array is simply a concatenated set of _n_ data encodings.  For
278  *   example, the type "A(6)" is simply a list of IPv6 addresses---one
279  *   after the other.  The type "A(6E)" likewise a concatenation of IPv6-
280  *   address/EUI-64 pairs.
281  *
282  *   If an array contains many fields, the fields will often be surrounded
283  *   by a structure ("t(...)").  This effectively prepends each item in
284  *   the array with its length.  This is useful for improving parsing
285  *   performance or to allow additional fields to be added in the future
286  *   in a backward compatible way.  If there is a high certainty that
287  *   additional fields will never be added, the struct may be omitted
288  *   (saving two bytes per item).
289  *
290  *   This specification does not define a way to embed an array as a field
291  *   alongside other fields.

295  *   Spinel definition compatibility guideline:
296  *
297  *   The compatibility policy for NCP versus RCP and host side are handled
298  *   differently in spinel.
299  *
300  *   New NCP firmware should work with an older host driver, i.e., NCP
301  *   implementation should remain backward compatible.
302  *
303  *    - Existing fields in the format of an already implemented spinel
304  *      property or command cannot change.
305  *
306  *    - New fields may be appended at the end of the format (or the end of
307  *      a struct) as long as the NCP implementation treats the new fields as
308  *      optional (i.e., a driver not aware of and therefore not using the
309  *      new fields should continue to function as before).
310  *

312  *
313  *   For RCP and host, the "RCP API Version" numbers are used to check the
314  *   compatibility between host implementation and RCP firmware. Generally,
315  *   a newer host side implementation would work with a range of previous
316  *   or older RCP firmware versions.
317  *
318  *   - SPINEL_RCP_API_VERSION specifies the current spinel RCP API version.
319  *     This number MUST be incremented anytime there is a change in any of RCP
320  *     specific spinel definitions.
321  *
322  *   - SPINEL_MIN_HOST_SUPPORTED_RCP_API_VERSION specifies the minimum spinel
323  *     RCP API Version which is supported by the host-side implementation.
324  *     To reduce the backward compatibility issues, this number should be kept
325  *     as constant as possible.
326  *
327  *   - On start, host implementation queries the RCP API version and accepts
328  *     any version starting from SPINEL_MIN_HOST_SUPPORTED_RCP_API_VERSION.
329  *
330  *   - Host implementation also queries the RCP about the minimum host RCP
331  *     API version it can work with, and then checks that its own version is
332  *     within the range.
333  *
334  *   Host and RCP compatibility guideline:
335  *
336  *   - New host spinel layer should work with an older RCP firmware, i.e., host
337  *     implementation should remain backward compatible.
338  *
339  *   - Existing fields in the format of an already implemented spinel
340  *     property or command must not change.
341  *
342  *   - New fields must be appended to the end of the existing spinel format.
343  *     *  New fields for new features:
344  *          Adding a new capability flag to the otRadioCaps to indicate the new
345  *          fields. The host parses the spinel format based on the pre-fetched
346  *          otRadioCaps. The host should be able to enable/disable the feature
347  *          in runtime based on the otRadioCaps. Refer to PR4919 and PR5139.
348  *     *  New fields for changing existing implementations:
349  *          This case should be avoided as much as possible. It will cause the
350  *          compatibility issue.
351  *
352  *   - Deprecated fields must not be removed from the spinel format and they
353  *     must be set to a suitable default value.
354  *
355  *   - Adding new spinel properties.
356  *     * If the old version RCP doesn't support the new spinel property, it
357  *       must return the spinel error SPINEL_STATUS_PROP_NOT_FOUND.
358  *
359  *     * If the host can handle the new spinel property by processing the error
360  *       SPINEL_STATUS_PROP_NOT_FOUND, the API of the new spinel property must
361  *       return OT_ERROR_NOT_IMPLEMENTED or default value.
362  *
363  *     * If the host can't handle the new spinel property by processing the
364  *       error SPINEL_STATUS_PROP_NOT_FOUND, a new capability flag must be

1484      * asynchronous updates. Enumeration `spinel_host_power_state_t` defines
1485      * the valid values (`SPINEL_HOST_POWER_STATE_*`):
1486      *
1487      *   `HOST_POWER_STATE_OFFLINE`: Host is physically powered off and
1488      *   cannot be woken by the NCP. All asynchronous commands are

1490      *
1491      *   `HOST_POWER_STATE_DEEP_SLEEP`: The host is in a low power state
1492      *   where it can be woken by the NCP but will potentially require more
1493      *   than two seconds to become fully responsive. The NCP MUST
1494      *   avoid sending unnecessary property updates, such as child table
1495      *   updates or non-critical messages on the debug stream. If the NCP

1498      *   should wake up, the NCP MUST wait for some activity from the
1499      *   host (indicating that it is fully awake) before sending frames.
1500      *
1501      *   `HOST_POWER_STATE_RESERVED`:  This value MUST NOT be set by the host. If
1502      *   received by the NCP, the NCP SHOULD consider this as a synonym
1503      *   of `HOST_POWER_STATE_DEEP_SLEEP`.
1504      *
1505      *   `HOST_POWER_STATE_LOW_POWER`: The host is in a low power state
1506      *   where it can be immediately woken by the NCP. The NCP SHOULD
1507      *   avoid sending unnecessary property updates, such as child table
1508      *   updates or non-critical messages on the debug stream.
1509      *
1510      *   `HOST_POWER_STATE_ONLINE`: The host is awake and responsive. No
1511      *   special filtering is performed by the NCP on asynchronous updates.
1512      *
1513      *   All other values are RESERVED. They MUST NOT be set by the
1514      *   host. If received by the NCP, the NCP SHOULD consider the value as
1515      *   a synonym of `HOST_POWER_STATE_LOW_POWER`.
1516      *
1517      * After setting this power state, any further commands from the host to
1518      * the NCP will cause `HOST_POWER_STATE` to automatically revert to
1519      * `HOST_POWER_STATE_ONLINE`.
1520      *
1521      * When the host is entering a low-power state, it should wait for the
1522      * response from the NCP acknowledging the command (with `CMD_VALUE_IS`).
1523      * Once that acknowledgment is received the host may enter the low-power
1524      * state.

1561      *   `LOW_POWER`, host is expected to "poke" the NCP (e.g., an external trigger
1562      *   like an interrupt) before it can communicate with the NCP (send a message
1563      *   to the NCP). The "poke" mechanism is determined by the platform code (based

1567      *   indicate that the NCP's power state has changed, i.e., host is expected to
1568      *   continue to "poke" NCP when it wants to talk to the NCP until the power
