Applications can submit a set of commands in one packet to the kernel,
and in some cases it is required such as reading the temperature
sensor results. This adds an option W1_CN_BUNDLE to the flags of
cn_msg to request the kernel to reply in one packet for efficiency.The cn_msg flags now check for unknown flag values and return an error
if one is seen. See "Proper handling of unknown flags in system
calls" http://lwn.net/Articles/588444/This corrects the ack values returned as per the protocol standard,
namely the original ack for status messages and seq + 1 for all others
such as the data returned from a read.Some of the common variable names have been standardized as follows.
struct cn_msg *cn
struct w1_netlink_msg *msg
struct w1_netlink_cmd *cmd
struct w1_master *devWhen an argument and a function scope variable would collide, add req_
to the argument.Signed-off-by: David Fries

This increases the amount of bundling to reduce the number of packets
sent. For the one wire use there can be multiple struct
w1_netlink_cmd in a struct w1_netlink_msg and multiple of those in
struct cn_msg, and with this change multiple of those in a struct
nlmsghdr, and at each level the len identifies there being multiple of
the next.Signed-off-by: David Fries

The grammar in most of this file is slightly off, and some sections are
hard to read due to lack of visual clues breaking up related material.Signed-off-by: Mike Frysinger
