10 1. Events. They are generated each time a new master or slave device
21   [struct cn_msg] - connector header.
23   [struct w1_netlink_msg] - w1 netlink header.
24 	__u8 type 	- message type.
30 				master add/remove events
32 				userspace command for bus master
37 	__u8 status	- error indication from kernel
38 	__u16 len	- size of data attached to this header data
40 		__u8 id[8];			 - slave unique device id
42 			__u32		id;	 - master's id
43 			__u32		res;	 - reserved
47   [struct w1_netlink_cmd] - command for given master or slave device.
48 	__u8 cmd	- command opcode.
49 			W1_CMD_READ 	- read command
50 			W1_CMD_WRITE	- write command
51 			W1_CMD_SEARCH	- search command
52 			W1_CMD_ALARM_SEARCH - alarm search command
53 			W1_CMD_TOUCH	- touch command
55 			W1_CMD_RESET	- send bus reset
56 			W1_CMD_SLAVE_ADD	- add slave to kernel list
57 			W1_CMD_SLAVE_REMOVE	- remove slave from kernel list
58 			W1_CMD_LIST_SLAVES	- get slaves list from kernel
59 	__u8 res	- reserved
60 	__u16 len	- length of data for this command
62 	__u8 data[0]	- data for this command
72 or master's id, which is assigned to bus master device
77 read request. Replies are not combined when sent - i.e. typical reply

85   w1_netlink_cmd.len = cmd->len;
88 which will contain list of all registered master ids in the following
97 Each message is at most 4k in size, so if number of master devices
106 	id is equal to the bus master id to use for searching]

140 Each command (either root, master or slave with or without w1_netlink_cmd
147 If reply is generated for master or root command (which do not have
169 master or slave request, according to w1_netlink_msg.type field.
170 Then master or slave device is searched for.
171 When found, master device (requested or those one on where slave device
178 When all commands (w1_netlink_cmd) are processed master device is unlocked
188 Sequence number for event messages is appropriate bus master sequence number
189 increased with each event message sent "through" this master.
