config NET_RADIO
	bool "Wireless LAN drivers (non-hamradio) & Wireless Extensions"
	select WIRELESS_EXT
	---help---
	  Support for wireless LANs and everything having to do with radio,
	  but not with amateur radio or FM broadcasting.

	  Saying Y here also enables the Wireless Extensions (creates
	  /proc/net/wireless and enables iwconfig access). The Wireless
	  Extension is a generic API allowing a driver to expose to the user
	  space configuration and statistics specific to common Wireless LANs.
	  The beauty of it is that a single set of tool can support all the
	  variations of Wireless LANs, regardless of their type (as long as
	  the driver supports Wireless Extension). Another advantage is that
	  these parameters may be changed on the fly without restarting the
	  driver (or Linux). If you wish to use Wireless Extensions with
	  wireless PCMCIA (PC-) cards, you need to say Y here; you can fetch
	  the tools from
	  <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.

config NET_WIRELESS_RTNETLINK
	bool "Wireless Extension API over RtNetlink"
	depends on NET_RADIO
	---help---
	  Support the Wireless Extension API over the RtNetlink socket
	  in addition to the traditional ioctl interface (selected above).

	  For now, few tools use this facility, but it might grow in the
	  future. The only downside is that it adds 4.5 kB to your kernel.

# Note : the cards are obsolete (can't buy them anymore), but the drivers
# are not, as people are still using them...

config STRIP
	tristate "STRIP (Metricom starmode radio IP)"
	depends on NET_RADIO && INET
	---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
	  (on the WWW at <http://mosquitonet.stanford.edu/>) 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"

	---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.

	  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.

	  This driver support the ISA version of the WaveLAN card.  A separate
	  driver for the PCMCIA (PC-card) hardware is available in David
	  Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
	  for location).

	  If you want to use an ISA WaveLAN card under Linux, say Y and read
	  the Ethernet-HOWTO, available from

          See <file:Documentation/networking/README.ipw2100> for information on
          the capabilities currently enabled in this driver and for tips
          for debugging issues and problems.

	  In order to use this driver, you will need a firmware image for it.
          You can obtain the firmware from
	  <http://ipw2100.sf.net/>.  Once you have the firmware image, you 
	  will need to place it in /lib/firmware.

          You will also very likely need the Wireless Tools in order to
          configure your card:

          <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
 
          If you want to compile the driver as a module ( = code which can be
          inserted in and removed from the running kernel whenever you want),

	  Enables promiscuous/monitor mode support for the ipw2100 driver.
	  With this feature compiled into the driver, you can switch to 
	  promiscuous mode via the Wireless Tool's Monitor mode.  While in this
	  mode, no packets can be sent.

config IPW2100_DEBUG
	bool "Enable full debugging output in IPW2100 module."
	depends on IPW2100
	---help---
	  This option will enable debug tracing output for the IPW2100.  

	  This will result in the kernel module being ~60k larger.  You can 
	  control which debug output is sent to the kernel log by setting the 
	  value in 

	  /sys/bus/pci/drivers/ipw2100/debug_level

	  This entry will only exist if this option is enabled.

	  If you are not trying to debug or develop the IPW2100 driver, you 
	  most likely want to say N here.

          Enables the creation of a second interface prefixed 'rtap'. 
          This second interface will provide every received in radiotap
	  format.

          This is useful for performing wireless network analysis while
          maintaining an active association.

          Example usage:

            % modprobe ipw2200 rtap_iface=1
            % ifconfig rtap0 up
            % tethereal -i rtap0

          If you do not specify 'rtap_iface=1' as a module parameter then 
          the rtap interface will not be created and you will need to turn 
          it on via sysfs:
	
            % echo 1 > /sys/bus/pci/drivers/ipw2200/*/rtap_iface

	  /sys/bus/pci/drivers/ipw2200/debug_level

	  This entry will only exist if this option is enabled.

	  To set a value, simply echo an 8-byte hex value to the same file:

	  % echo 0x00000FFO > /sys/bus/pci/drivers/ipw2200/debug_level

	  You can find the list of debug mask values in

	  This option includes the guts of the driver, but in order to
	  actually use a card you will also need to enable support for PCMCIA
	  Hermes cards, PLX9052 based PCI adaptors or the Apple Airport below.

	  You will also very likely also need the Wireless Tools in order to
