Dmitry Eremin-Solenikov a53d34c346 net: move 6lowpan compression code to separate module
IEEE 802.15.4 and Bluetooth networking stacks share 6lowpan compression
code. Instead of introducing Makefile/Kconfig hacks, build this code as
a separate module referenced from both ieee802154 and bluetooth modules.

This fixes the following build error observed in some kernel
configurations:

net/built-in.o: In function `header_create': 6lowpan.c:(.text+0x166149): undefined reference to `lowpan_header_compress'
net/built-in.o: In function `bt_6lowpan_recv': (.text+0x166b3c): undefined reference to `lowpan_process_data'

Jukka Rissanen 8df8c56a5a 6lowpan: Moving generic compression code into 6lowpan_iphc.c
Because the IEEE 802154 and Bluetooth share the IP header compression
and uncompression code, the common code is moved to 6lowpan_iphc.c
file.

Alexander Smirnov 44331fe2aa IEEE802.15.4: 6LoWPAN basic support
This patch provides base support for transmission of IPv6 packets as
well as the formation of IPv6 link-local addresses and statelessly
autoconfigured addresses on top of IEEE 802.15.4 networks.

For more information please look at the RFC4944 "Compression Format
for IPv6 Datagrams in Low Power and Losst Networks (6LoWPAN).

David S. Miller bfac3693c4 ieee802154: Remove hacked CFLAGS in net/ieee802154/Makefile
It adds -Wall (which the kernel carefully controls already) and of all
things -DDEBUG (which should be set by other means if desired, please
we have dynamic-debug these days).

Kill this noise.

Dmitry Eremin-Solenikov 78fe738d1a ieee802154: split away MAC commands implementation
Move all mac-related stuff to separate file so that ieee802154/netlink.c
contains only generic code.

Dmitry Eremin-Solenikov cb6b376357 ieee802154: merge nl802154 and wpan-class in single module
There is no real need to have ieee802154 interfaces separate
into several small modules, as neither of them has it's own use.

Sergey Lapin 9ec7671603 net: add IEEE 802.15.4 socket family implementation
Add support for communication over IEEE 802.15.4 networks. This implementation
is neither certified nor complete, but aims to that goal. This commit contains
only the socket interface for communication over IEEE 802.15.4 networks.
One can either send RAW datagrams or use SOCK_DGRAM to encapsulate data
inside normal IEEE 802.15.4 packets.

Configuration interface, drivers and software MAC 802.15.4 implementation will
follow.

Initial implementation was done by Maxim Gorbachyov, Maxim Osipov and Pavel
Smolensky as a research project at Siemens AG. Later the stack was heavily
reworked to better suit the linux networking model, and is now maitained
as an open project partially sponsored by Siemens.
