+BTSnoop/Monitor protocol formats
+********************************
+
+Opcode definitions
+==================
+
+New Index
+---------
+
+	Code:        0x0000
+	Parameters:  Type (1 Octet
+		     Bus (1 Octet)
+		     BD_Addr (6 Octets)
+		     Name (8 Octets)
+
+	This opcode indicates that a new controller instance with a
+	given index was added. With some protocols, like the TTY-based
+	one there is only a single supported controller, meaning the
+	index is implicitly 0.
+
+Deleted Index
+-------------
+
+	Code:        0x0001
+
+	This opcode indicates that the controller with a specific index
+	was removed.
+
+Command Packet
+--------------
+
+	Code:        0x0002
+
+	HCI command packet.
+
+Event Packet
+------------
+
+	Code:        0x0003
+
+	HCI event packet.
+
+ACL TX Packet
+-------------
+
+	Code:        0x0004
+
+	Outgoing ACL packet.
+
+ACL RX Packet
+-------------
+
+	Code:        0x0005
+
+	Incoming ACL packet.
+
+SCO TX Packet
+--------------
+
+	Code:        0x0006
+
+	Outgoing SCO packet.
+
+SCO RX Packet
+-------------
+
+	Code:        0x0007
+
+	Incomnig SCO packet.
+
+Open Index
+----------
+
+	Code:        0x0008
+
+	The HCI transport for the specified controller has been opened.
+
+Close Index
+-----------
+
+	Code:        0x0009
+
+	The HCI transport for the specified controller has been closed.
+
+Index Information
+-----------------
+
+	Code:        0x000a
+	Parameters:  BD_Addr (6 Octets)
+		     Manufacturer (2 Octets)
+
+	Information about a specific controller.
+
+Vendor Diagnostics
+------------------
+
+	Code:        0x000b
+
+	Vendor diagnostic information.
+
+System Note
+-----------
+
+	Code:        0x000c
+
+	System note.
+
+User Logging
+------------
+
+	Code:        0x000d
+	Parameters:  Priority (1 Octet)
+		     Ident_Length (1 Octet)
+		     Ident (Ident_Length Octets)
+
+	User logging information.
+
+
+TTY-based protocol
+==================
+
+This section covers the protocol that can be parsed by btmon when
+passing it the --tty parameter. The protocol is little endian, packet
+based, and has the following header for each packet:
+
+struct tty_hdr {
+	uint16_t data_len;
+	uint16_t opcode;
+	uint8_t  flags;
+	uint8_t  hdr_len;
+	uint8_t  ext_hdr[0];
+} __attribute__ ((packed));
+
+The actual payload starts at ext_hdr + hdr_len and has the length of
+data_len - 4 - hdr_len. Each field of the header is defined as follows:
+
+data_len:
+	This is the total length of the entire packet, excuding the
+	data_len field itself.
+
+opcode:
+	The BTSnoop opcode
+
+flags:
+	Special flags for the packet. Currently no flags are defined.
+
+hdr_len:
+	Length of the extended header.
+
+ext_hdr:
+	This is a sequence of header extension fields formatted as:
+
+	struct {
+		uint8_t type;
+		uint8_t value[length];
+	}
+
+	The length of the value is dependent on the type. Currently the
+	following types are defined:
+
+	Type                 Length    Meaning
+	----------------------------------------------------------------
+	1  Command drops     1 byte    Dropped HCI command packets
+	2  Event drops       1 byte    Dropped HCI event packets
+	3  ACL TX drops      1 byte    Dropped ACL TX packets
+	4  ACL RX drops      1 byte    Dropped ACL RX packets
+	5  SCO TX drops      1 byte    Dropped SCO TX packets
+	6  SCO RX drops      1 byte    Dropped SCO RX packets
+	7  Other drops       1 byte    Dropped other packets
+	8  32-bit timestamp  4 bytes   Timestamp in 1/10th ms
+
+	The drops fields indicate the number of packets that the
+	implementation had to drop (e.g. due to lack of buffers) since
+	the last reported drop count.
+
+	The fields of the extended header must be sorted by increasing
+	type. This is essential so that unknown types can be ignored and
+	the parser can jump to processing the payload.
