menuconfig WLAN_PRE80211
bool "Wireless LAN (pre-802.11)"
depends on NETDEVICES
---help---
Say Y if you have any pre-802.11 wireless LAN hardware.
This option does not affect the kernel build, it only
lets you choose drivers.
config STRIP
tristate "STRIP (Metricom starmode radio IP)"
depends on INET && WLAN_PRE80211
select WIRELESS_EXT
---help---
Say Y if you have a Metricom radio and intend to use Starmode Radio
IP. STRIP is a radio protocol developed for the MosquitoNet project
to send Internet traffic using Metricom radios. Metricom radios are
small, battery powered, 100kbit/sec packet radio transceivers, about
the size and weight of a cellular telephone. (You may also have heard
them called "Metricom modems" but we avoid the term "modem" because
it misleads many people into thinking that you can plug a Metricom
modem into a phone line and use it as a modem.)
You can use STRIP on any Linux machine with a serial port, although
it is obviously most useful for people with laptop computers. If you
think you might get a Metricom radio in the future, there is no harm
in saying Y to STRIP now, except that it makes the kernel a bit
bigger.
To compile this as a module, choose M here: the module will be
called strip.
config ARLAN
tristate "Aironet Arlan 655 & IC2200 DS support"
depends on ISA && !64BIT && WLAN_PRE80211
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.

tristate "AT&T/Lucent old WaveLAN & DEC RoamAbout DS ISA support"

select WIRELESS_EXT
select WEXT_SPY
select WEXT_PRIV
---help---
The Lucent WaveLAN (formerly NCR and AT&T; or DEC RoamAbout DS) is
a Radio LAN (wireless Ethernet-like Local Area Network) using the
radio frequencies 900 MHz and 2.4 GHz.
If you want to use an ISA WaveLAN card under Linux, say Y and read
the Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. Some more specific
information is contained in
<file:Documentation/networking/wavelan.txt> and in the source code
<file:drivers/net/wireless/wavelan.p.h>.
You will also need the wireless tools package available from
<http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
Please read the man pages contained therein.
To compile this driver as a module, choose M here: the module will be
called wavelan.

(PC-card) wireless Ethernet networking card to your computer. This
driver is for the non-IEEE-802.11 Wavelan cards.
To compile this driver as a module, choose M here: the module will be
called wavelan_cs. If unsure, say N.

config ARLAN
tristate "Aironet Arlan 655 & IC2200 DS support"
depends on ISA && !64BIT
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>.

depends on PCMCIA
select WIRELESS_EXT

help
Say Y here if you intend to attach this type of PCMCIA (PC-card)
wireless Ethernet networking card to your computer.
To compile this driver as a module, choose M here: the module will be
called netwave_cs. If unsure, say N.
