====================
pull request: bluetooth-next 2016-12-03

Here's a set of Bluetooth & 802.15.4 patches for net-next (i.e. 4.10
kernel):

 - Fix for a potential NULL deref in the ieee802154 netlink code
 - Fix for the ED values of the at86rf2xx driver
 - Documentation updates to ieee802154
 - Cleanups to u8 vs __u8 usage
 - Timer API usage cleanups in HCI drivers

Please let me know if there are any issues pulling. Thanks.

The IEEE 802.15.4 working group focuses on standardization of the bottom
two layers: Medium Access Control (MAC) and Physical access (PHY). And there
are mainly two options available for upper layers:
- ZigBee - proprietary protocol from the ZigBee Alliance
- 6LoWPAN - IPv6 networking over low rate personal area networks
The linux-wpan project goal is to provide a complete implementation
The goal of the Linux-wpan is to provide a complete implementation
of the IEEE 802.15.4 and 6LoWPAN protocols. IEEE 802.15.4 is a stack
of protocols for organizing Low-Rate Wireless Personal Area Networks.
The stack is composed of three main parts:
- IEEE 802.15.4 layer; We have chosen to use plain Berkeley socket API,
the generic Linux networking stack to transfer IEEE 802.15.4 messages
and a special protocol over genetlink for configuration/management
the generic Linux networking stack to transfer IEEE 802.15.4 data
messages and a special protocol over netlink for configuration/management
- MAC - provides access to shared channel and reliable data delivery
- PHY - represents device drivers

One can use SOCK_RAW for passing raw data towards device xmit function. YMMV.
Kernel side
=============
Like with WiFi, there are several types of devices implementing IEEE 802.15.4.
1) 'HardMAC'. The MAC layer is implemented in the device itself, the device
exports MLME and data API.

2) 'SoftMAC' or just radio. These types of devices are just radio transceivers
possibly with some kinds of acceleration like automatic CRC computation and
comparation, automagic ACK handling, address matching, etc.

SoftMAC (fakelb - IEEE 802.15.4 loopback driver) interface. This option

In Semptember 2011 the standard update was published - [RFC6282].
In September 2011 the standard update was published - [RFC6282].
It deprecates HC1 and HC2 compression and defines IPHC encoding format which is
used in this Linux implementation.
All the code related to 6lowpan you may find in files: net/6lowpan/*
and net/ieee802154/6lowpan/*
To setup 6lowpan interface you need (busybox release > 1.17.0):
1. Add IEEE802.15.4 interface and initialize PANid;
To setup a 6LoWPAN interface you need:
1. Add IEEE802.15.4 interface and set channel and PAN ID;
2. Add 6lowpan interface by command like:
# ip link add link wpan0 name lowpan0 type lowpan
3. Set MAC (if needs):
# ip link set lowpan0 address de:ad:be:ef:ca:fe:ba:be
4. Bring up 'lowpan0' interface
3. Bring up 'lowpan0' interface
