Subject: [RFC][WIP] IEEE 802.15.4 implementation for Linux
Newsgroups: gmane.linux.kernel.wireless.general
Date: Tuesday 26th May 2009 11:21:57 UTC (over 8 years ago)
Hi,

As a part of research activities in 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/

Several comments about our implementation:
* As with 802.11 there are two types of devices: the smart ones that
implement
  most parts of the protocol by themselves and more or less dumb ones which
  simply send and receive what they are told. Currently we do only support
the
  second type of devices (SoftMAC)
* The implementation is split between code driving radio, (master, mwpanX
  interface: mdev.c), code processing frames according the IEEE 802.15.4
  rules (slave wpanX devices) and finally sockets (af_ieee802154.c,
dgram.c,
  raw.c).
* We do present two example drivers using our stack. One is purely virtual
  one either looping the packets back or connecting several virtual
interfaces
  (the one at fakelb.c), and the driver for the Freescale MC13192
evaluation
  boards (13192-SARD, 13192-EVK) using our custom firmware (currently only
  available at request, we are working on publishing it). The driver for
the
  Atmel at86rf230/at86rf231 chips will follow in several weeks.

The following changes since commit
