config ADIS16255
tristate "Ananlog Devices ADIS16250/16255"
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
will be called adis16255.

config ARLAN
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.

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 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/
# aggregate_ogm originators transtable_global vis_mode
# orig_interval 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/class/net/bat0/mesh/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
# 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 respon-
sive to topology changes, but will also increase the overhead.
This is batman-advanced implemented as Linux kernel driver. It does not depend
on any network (other) driver, and can be used on wifi as well as ethernet,
vpn, etc ... (anything with ethernet-style layer 2).
USAGE
-----
insmod the batman-adv.ko in your kernel:
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.
# insmod batman-adv.ko
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):
the module is now waiting for activation. You must add some interfaces
on which batman can operate. Each interface must be added separately:
# NodeA: ifconfig bat0 192.168.0.1
# NodeB: ifconfig bat0 192.168.0.2
# NodeB: ping 192.168.0.1
# echo wlan0 > /proc/net/batman-adv/interfaces
Note: In order to avoid problems remove all IP addresses previ-
ously assigned to interfaces now used by batman advanced, e.g.
( # echo wlan1 > /proc/net/batman-adv/interfaces )
( # echo eth0 > /proc/net/batman-adv/interfaces )
( ... )
# ifconfig eth0 0.0.0.0
Now batman starts broadcasting on this interface.
You can now view the table of originators (mesh participants) with:
# cat /proc/net/batman-adv/originators
VISUALIZATION
-------------
The module will create a new interface "bat0", which can be used as a
regular interface:
If you want topology visualization, at least one mesh node must
be configured as VIS-server:
# ifconfig bat0 inet 192.168.0.1 up
# ping 192.168.0.2
...
# echo "server" > /sys/class/net/bat0/mesh/vis_mode
If you want topology visualization, your meshnode must be configured
as VIS-server:
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.
# echo "server" > /proc/net/batman-adv/vis
When configured as server, you can get a topology snapshot of
your mesh:
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.
# cat /sys/class/net/bat0/mesh/vis_data
When configured as server, you can get a topology snapshot of your mesh:
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.
# cat /proc/net/batman-adv/vis
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 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.
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
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).
# echo 1000 > /proc/net/batman-adv/orig_interval
To deactivate batman, do:
# echo "" > /proc/net/batman-adv/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 commands: dmesg,
logread, or looking in the files /var/log/kern.log or
/var/log/syslog. All batman-adv messages are prefixed with
