[RFC][WIP] IEEE 802.15.4 implementation for Linux v1

[Dmitry Eremin-Solenikov]

Hi,

As a part of research activities the Embedded Systems - Open Platform Group
from Siemens Corporate Technology we are working on adding support for
the IEEE 802.15.4 Wireless Personal Area Networks to the Linux. Our current
implementation is neither certified nor even feature complete. However
we'd like to present current state of our patchset to the Linux developers
community to gain comments, fixes, ideas, etc. This is not yet a pull request,
but more like an RFC.

The project page is available at http://apps.sourceforge.net/trac/linux-zigbee
with source code of kernel part available from git at
http://zigbee-linux.git.sourceforge.net, mirrored for convenience at
git://git.kernel.org/pub/scm/linux/kernel/git/lumag/lowpan.git

The source code for userspace utils is available from git at
http://linux-zigbee.git.sourceforge.net/

Changes since previous RFC:
  * Split the code into socket family, netlink interface and separate
    MAC 802.15.4 implementation.
  * Add a sample driver for devices implementing mac level of IEEE 802.15.4
    on their own.
  * Major cleanup of public interfaces.
  * Drop our CRC implementation and use a variant of CRC-ITU-T one
  * Add preliminary version of AT86RF231 Atmel chip driver

The following changes since commit 59a3759d0fe8d969888c741bb33f4946e4d3750d:
  Linus Torvalds (1):
        Linux 2.6.30-rc7
