-	depends on SPI && SYSFS
-	---help---
-	If you say yes here you get support for the Analog Devices
-	ADIS16250/16255 Low Power Gyroscope. The driver exposes
-	orientation and gyroscope value, as well as sample rate
-	to the sysfs.
-
-	This driver can also be built as a module. If so, the module

-BATMAN-ADV
-----------
-
-Batman  advanced  is  a new approach to wireless networking which
-does no longer operate on the IP basis. Unlike the batman daemon,
-which  exchanges  information  using UDP packets and sets routing
-tables, batman-advanced operates on ISO/OSI Layer 2 only and uses
-and  routes  (or  better: bridges) Ethernet Frames. It emulates a
-virtual network switch of all nodes participating.  Therefore all
-nodes  appear  to be link local, thus all higher operating proto-
-cols won't be affected by any changes within the network. You can
-run almost any protocol above batman advanced, prominent examples
-are: IPv4, IPv6, DHCP, IPX.
-
-Batman advanced was implemented as a Linux kernel driver  to  re-
-duce the overhead to a minimum. It does not depend on any (other)
-network driver, and can be used on wifi as well as ethernet  lan,
-vpn,  etc ... (anything with ethernet-style layer 2).
-
-CONFIGURATION
--------------
-
-Load the batman-adv module into your kernel:
-
-# insmod batman-adv.ko
-
-The  module  is now waiting for activation. You must add some in-
-terfaces on which batman can operate. After  loading  the  module
-batman  advanced  will scan your systems interfaces to search for
-compatible interfaces. Once found, it will create  subfolders  in
-the /sys directories of each supported interface, e.g.
-
-# ls /sys/class/net/eth0/batman_adv/
-# iface_status  mesh_iface
-
-If an interface does not have the "batman_adv" subfolder it prob-
-ably is not supported. Not supported  interfaces  are:  loopback,
-non-ethernet and batman's own interfaces.
-
-Note:  After the module was loaded it will continuously watch for
-new interfaces to verify the compatibility. There is no  need  to
-reload the module if you plug your USB wifi adapter into your ma-
-chine after batman advanced was initially loaded.
-
-To activate a  given  interface  simply  write  "bat0"  into  its
-"mesh_iface" file inside the batman_adv subfolder:
-
-# echo bat0 > /sys/class/net/eth0/batman_adv/mesh_iface
-
-Repeat  this step for all interfaces you wish to add.  Now batman
-starts using/broadcasting on this/these interface(s).
-
-By reading the "iface_status" file you can check its status:
-
-# cat /sys/class/net/eth0/batman_adv/iface_status
-# active
-
-To deactivate an interface you have  to  write  "none"  into  its
-"mesh_iface" file:
-
-# echo none > /sys/class/net/eth0/batman_adv/mesh_iface
-
-
-All  mesh  wide  settings  can be found in batman's own interface
-folder:
-
-#  ls  /sys/class/net/bat0/mesh/
-#  aggregated_ogms  bonding  orig_interval  vis_mode
-
-
-There is a special folder for debugging informations:
-
-#  ls /sys/kernel/debug/batman_adv/bat0/
-#  originators  socket  transtable_global  transtable_local
-#  vis_data
-
-
-Some of the files contain all sort of status information  regard-
-ing  the  mesh  network.  For  example, you can view the table of
-originators (mesh participants) with:
-
-# cat /sys/kernel/debug/batman_adv/bat0/originators
-
-Other files allow to change batman's behaviour to better fit your
-requirements.  For instance, you can check the current originator
-interval (value in milliseconds which determines how often batman
-sends its broadcast packets):
-
-# cat /sys/class/net/bat0/mesh/orig_interval
-# 1000
-
-and also change its value:
-
-# echo 3000 > /sys/class/net/bat0/mesh/orig_interval
-
-In very mobile scenarios, you might want to adjust the originator
-interval to a lower value. This will make the mesh  more  respon-
-sive to topology changes, but will also increase the overhead.
-
-
-USAGE
------
-
-To  make use of your newly created mesh, batman advanced provides
-a new interface "bat0" which you should use from this  point  on.
-All  interfaces  added  to  batman  advanced are not relevant any
-longer because batman handles them for you. Basically, one "hands
-over" the data by using the batman interface and batman will make
-sure it reaches its destination.
-
-The "bat0" interface can be used like any  other  regular  inter-
-face.  It needs an IP address which can be either statically con-
-figured or dynamically (by using DHCP or similar services):
-
-# NodeA: ifconfig bat0 192.168.0.1
-# NodeB: ifconfig bat0 192.168.0.2
-# NodeB: ping 192.168.0.1
-
-Note:  In  order to avoid problems remove all IP addresses previ-
-ously assigned to interfaces now used by batman advanced, e.g.
-
-# ifconfig eth0 0.0.0.0
-
-
-VISUALIZATION
--------------
-
-If you want topology visualization, at least one mesh  node  must
-be configured as VIS-server:
-
-# echo "server" > /sys/class/net/bat0/mesh/vis_mode
-
-Each  node  is  either configured as "server" or as "client" (de-
-fault: "client").  Clients send their topology data to the server
-next to them, and server synchronize with other servers. If there
-is no server configured (default) within the  mesh,  no  topology
-information   will  be  transmitted.  With  these  "synchronizing
-servers", there can be 1 or more vis servers sharing the same (or
-at least very similar) data.
-
-When  configured  as  server,  you can get a topology snapshot of
-your mesh:
-
-# cat /sys/kernel/debug/batman_adv/bat0/vis_data
-
-This raw output is intended to be easily parsable and convertable
-with  other tools. Have a look at the batctl README if you want a
-vis output in dot or json format for instance and how those  out-
-puts could then be visualised in an image.
-
-The raw format consists of comma separated values per entry where
-each entry is giving information about a  certain  source  inter-
-face.  Each  entry can/has to have the following values:
--> "mac" - mac address of an originator's source interface
-           (each line begins with it)
--> "TQ mac  value"  -  src mac's link quality towards mac address
-                       of a neighbor originator's interface which
-                       is being used for routing
--> "HNA mac" - HNA announced by source mac
--> "PRIMARY" - this  is a primary interface
--> "SEC mac" - secondary mac address of source
-               (requires preceding PRIMARY)
-
-The TQ value has a range from 4 to 255 with 255 being  the  best.
-The HNA entries are showing which hosts are connected to the mesh
-via bat0 or being bridged into the mesh network.  The PRIMARY/SEC
-values are only applied on primary interfaces
-
-
-LOGGING/DEBUGGING
------------------
-
-All error messages, warnings and information messages are sent to
-the kernel log. Depending on your operating  system  distribution
-this  can  be read in one of a number of ways. Try using the com-
-mands: dmesg, logread, or looking in the files  /var/log/kern.log
-or  /var/log/syslog.  All  batman-adv  messages are prefixed with
-"batman-adv:" So to see just these messages try
-
-# dmesg | grep batman-adv
-
-When investigating problems with your mesh network  it  is  some-
-times  necessary  to see more detail debug messages. This must be
-enabled when compiling the batman-adv module. When building  bat-
-man-adv  as  part of kernel, use "make menuconfig" and enable the
-option "B.A.T.M.A.N. debugging".
-
-Those additional  debug messages can be accessed  using a special
-file in debugfs
-
-# cat /sys/kernel/debug/batman_adv/bat0/log
-
-The additional debug output is by default disabled. It can be en-
-abled  during run time. Following log_levels are defined:
-
-0 - All  debug  output  disabled
-1 - Enable messages related to routing / flooding / broadcasting
-2 - Enable route or hna added / changed / deleted
-3 - Enable all messages
-
-The debug output can be changed at runtime  using  the  file
-/sys/class/net/bat0/mesh/log_level. e.g.
-
-# echo 2 > /sys/class/net/bat0/mesh/log_level
-
-will enable debug messages for when routes or HNAs change.
-
-
-BATCTL
-------
-
-As batman advanced operates on layer 2 all hosts participating in
-the  virtual switch are completely transparent for all  protocols
-above layer 2. Therefore the common diagnosis tools do  not  work
-as  expected.  To  overcome these problems batctl was created. At
-the  moment the  batctl contains ping,  traceroute,  tcpdump  and
-interfaces to the kernel module settings.
-
-For more information, please see the manpage (man batctl).
-
-batctl is available on http://www.open-mesh.org/

-Contact:        Marek Lindner <lindner_marek@yahoo.de>
-Description:
-                Indicates whether the batman protocol messages of the
-                mesh <mesh_iface> shall be aggregated or not.

-Date:           June 2010
-Contact:        Simon Wunderlich <siwu@hrz.tu-chemnitz.de>
-Description:
-                Indicates whether the data traffic going through the
-                mesh will be sent using multiple interfaces at the
-                same time (if available).

-Date:           October 2010
-Contact:        Andreas Langer <an.langer@gmx.de>
-Description:
-                Indicates whether the data traffic going through the
-                mesh will be fragmented or silently discarded if the
-                packet size exceeds the outgoing interface MTU.

-What:           /sys/class/net/<mesh_iface>/mesh/orig_interval
-Date:           May 2010
-Contact:        Marek Lindner <lindner_marek@yahoo.de>
-Description:
-                Defines the interval in milliseconds in which batman
-                sends its protocol messages.
-
-What:           /sys/class/net/<mesh_iface>/mesh/vis_mode
-Date:           May 2010
-Contact:        Marek Lindner <lindner_marek@yahoo.de>
-Description:
-                Each batman node only maintains information about its
-                own local neighborhood, therefore generating graphs
-                showing the topology of the entire mesh is not easily
-                feasible without having a central instance to collect
-                the local topologies from all nodes. This file allows
-                to activate the collecting (server) mode.
