depends on NET_RADIO && (ISA || PCI || PPC_PMAC || PCMCIA)
config IPW2100
tristate "Intel PRO/Wireless 2100 Network Connection"
depends on NET_RADIO && PCI && IEEE80211
select FW_LOADER
---help---
A driver for the Intel PRO/Wireless 2100 Network
Connection 802.11b wireless network adapter.
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 /etc/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 remvoed from the running kernel whenever you want),
say M here and read <file:Documentation/modules.txt>. The module
will be called ipw2100.ko.
config IPW2100_MONITOR
bool "Enable promiscuous mode"
depends on IPW2100
---help---
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 IPW_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.
config IPW2200
tristate "Intel PRO/Wireless 2200BG and 2915ABG Network Connection"

Connection adapters.

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

config IPW_DEBUG
bool "Enable full debugging output in IPW2200 module."
depends on IPW2200
---help---
This option will enable debug tracing output for the IPW2200.
This will result in the kernel module being ~100k larger. You can
control which debug output is sent to the kernel log by setting the
value in
/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
drivers/net/wireless/ipw2200.h
If you are not trying to debug or develop the IPW2200 driver, you
most likely want to say N here.

config HOSTAP
tristate "IEEE 802.11 for Host AP (Prism2/2.5/3 and WEP/TKIP/CCMP)"
depends on NET_RADIO
---help---
Shared driver code for IEEE 802.11b wireless cards based on
Intersil Prism2/2.5/3 chipset. This driver supports so called
Host AP mode that allows the card to act as an IEEE 802.11
access point.
See <http://hostap.epitest.fi/> for more information about the
Host AP driver configuration and tools. This site includes
information and tools (hostapd and wpa_supplicant) for WPA/WPA2
support.
This option includes the base Host AP driver code that is shared by
different hardware models. You will also need to enable support for
PLX/PCI/CS version of the driver to actually use the driver.
The driver can be compiled as a module and it will be called
"hostap.ko".
config HOSTAP_FIRMWARE
bool "Support downloading firmware images with Host AP driver"
depends on HOSTAP
---help---
Configure Host AP driver to include support for firmware image
download. Current version supports only downloading to volatile, i.e.,
RAM memory. Flash upgrade is not yet supported.
Firmware image downloading needs user space tool, prism2_srec. It is
available from http://hostap.epitest.fi/.
config HOSTAP_PLX

Host AP driver's version for Prism2/2.5/3 PC Cards in PLX9052 based
PCI adaptors.
"Host AP support for Prism2/2.5/3 IEEE 802.11b" is required for this
driver and its help text includes more information about the Host AP
driver.
The driver can be compiled as a module and will be named
"hostap_plx.ko".
config HOSTAP_PCI

driver.
