+	---help---
+	If you say yes here you get support for the Analog Devices

-	tristate "Aironet Arlan 655 & IC2200 DS support"
-	depends on ISA && !64BIT && WLAN
-	select WIRELESS_EXT
-	---help---
-	  Aironet makes Arlan, a class of wireless LAN adapters. These use the
-	  www.Telxon.com chip, which is also used on several similar cards.
-	  This driver is tested on the 655 and IC2200 series cards. Look at
-	  <http://www.ylenurme.ee/~elmer/655/> for the latest information.
-
-	  The driver is built as two modules, arlan and arlan-proc. The latter
-	  is the /proc interface and is not needed most of time.
-
-	  On some computers the card ends up in non-valid state after some
-	  time. Use a ping-reset script to clear it.

drivers/staging/arlan/TODO

-TODO:
-	- step up and maintain this driver to ensure that it continues
-	  to work.  Having the hardware for this is pretty much a
-	  requirement.  If this does not happen, the will be removed in
-	  the 2.6.35 kernel release.
-
-Please send patches to Greg Kroah-Hartman <greg@kroah.com>.

 BATMAN-ADV
 ----------
 
-Batman-advanced is a new approach to wireless networking which does no longer
-operate on the IP basis. Unlike B.A.T.M.A.N, 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 protocols won't be
-affected by any changes within the network. You can run almost any protocol
-above B.A.T.M.A.N. 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).
 
-USAGE
------
+CONFIGURATION
+-------------
 
-insmod the batman-adv.ko in your kernel:
+Load the batman-adv module into your kernel:
 
 # insmod batman-adv.ko
 
-the module is now waiting for activation. You must add some interfaces
-on which batman can operate. Each interface must be added separately:
+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).
 
-# echo wlan0 > /proc/net/batman-adv/interfaces
+By reading the "iface_status" file you can check its status:
 
-( # echo wlan1 > /proc/net/batman-adv/interfaces )
-( # echo eth0 > /proc/net/batman-adv/interfaces )
-( ... )
+# cat /sys/class/net/eth0/batman_adv/iface_status
+# active
 
-Now batman starts broadcasting on this interface.
-You can now view the table of originators (mesh participants) with:
+To deactivate an interface you have  to  write  "none"  into  its
+"mesh_iface" file:
 
-# cat /proc/net/batman-adv/originators
+# echo none > /sys/class/net/eth0/batman_adv/mesh_iface
 
-The module will create a new interface "bat0", which can be used as a
-regular interface:
 
-# ifconfig bat0 inet 192.168.0.1 up
-# ping 192.168.0.2
-...
+All  mesh  wide  settings  can be found in batman's own interface
+folder:
 
-If you want topology visualization, your meshnode must be configured
-as VIS-server:
+#  ls  /sys/class/net/bat0/mesh/
+#  aggregate_ogm   originators        transtable_global  vis_mode
+#  orig_interval   transtable_local   vis_data
 
-# echo "server" > /proc/net/batman-adv/vis
 
-Each node is either configured as "server" or as "client" (default:
-"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.
+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:
 
-When configured as server, you can get a topology snapshot of your mesh:
+# cat /sys/class/net/bat0/mesh/originators
 
-# cat /proc/net/batman-adv/vis
+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):
 
-The output is in a generic raw format. Use the batctl tool (See below)
-to convert this to other formats more suitable for graphing, eg
-graphviz dot, or JSON data-interchange format.
+# cat /sys/class/net/bat0/mesh/orig_interval
+# status: 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 responsive to
-topology changes, but will also increase the overhead. Please make sure
-that all nodes in your mesh use the same interval. The default value
-is 1000 ms (1 second).
+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.
 
-# echo 1000 > /proc/net/batman-adv/orig_interval
+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):
 
-To deactivate batman, do:
+# 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/class/net/bat0/mesh/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

-kernel log. Depending on your operating system distribution this can be
