   121	 * struct spihid_msg_hdr - common header of protocol messages.
   122	 *
   123	 * Each message begins with fixed header, followed by a message-type specific
   124	 * payload, and ends with a 16-bit crc. Because of the varying lengths of the
   125	 * payload, the crc is defined at the end of each payload struct, rather than
   126	 * in this struct.
   127	 *
   128	 * @unknown0:	request type? output, input (0x10), feature, protocol
   129	 * @unknown1:	maybe report id?
   130	 * @unknown2:	mostly zero, in info request maybe device num
   131	 * @msgid:	incremented on each message, rolls over after 255; there is a
   132	 *		separate counter for each message type.
   133	 * @rsplen:	response length (the exact nature of this field is quite
   134	 *		speculative). On a request/write this is often the same as
   135	 *		@length, though in some cases it has been seen to be much larger
   136	 *		(e.g. 0x400); on a response/read this the same as on the
   137	 *		request; for reads that are not responses it is 0.
   138	 * @length:	length of the remainder of the data in the whole message
   139	 *		structure (after re-assembly in case of being split over
   140	 *		multiple spi-packets), minus the trailing crc. The total size
   141	 *		of a message is therefore @length + 10.
