- depends on PCI && WLAN_80211
- select WIRELESS_EXT
- select FW_LOADER
- select IEEE80211
- ---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 /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>.
-
- It is recommended that you compile this driver as a module (M)
- rather than built-in (Y). This driver requires firmware at device
- initialization time, and when built-in this typically happens
- before the filesystem is accessible (hence firmware will be
- unavailable and initialization will fail). If you do choose to build
- this driver into your kernel image, you can avoid this problem by
- including the firmware and a firmware loader in an initramfs.
-
-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 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.

-
-config IPW2200_PROMISCUOUS
- bool "Enable creation of a RF radiotap promiscuous interface"
- depends on IPW2200_MONITOR
- select IPW2200_RADIOTAP
- ---help---
- 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
-
-config IPW2200_QOS
- bool "Enable QoS support"
- depends on IPW2200 && EXPERIMENTAL
-
-config IPW2200_DEBUG
- bool "Enable full debugging output in IPW2200 module."
- depends on IPW2200
- ---help---
- This option will enable low level debug tracing output for IPW2200.
-
- Note, normal debug code is already compiled in. This low level
- debug option enables debug on hot paths (e.g Tx, Rx, ISR) and
- will result in the kernel module being ~70 larger. Most users
- will typically not need this high verbosity debug information.
-
- If you are not sure, say N here.

+ 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 /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>.
+
+ It is recommended that you compile this driver as a module (M)
+ rather than built-in (Y). This driver requires firmware at device
+ initialization time, and when built-in this typically happens
+ before the filesystem is accessible (hence firmware will be
+ unavailable and initialization will fail). If you do choose to build
+ this driver into your kernel image, you can avoid this problem by
+ including the firmware and a firmware loader in an initramfs.
+
+config IPW2100_MONITOR

+ ---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.
+

+ ---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

+ ---help---
+ 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

+ ---help---
+ This option will enable low level debug tracing output for IPW2200.
+
+ Note, normal debug code is already compiled in. This low level
+ debug option enables debug on hot paths (e.g Tx, Rx, ISR) and
+ will result in the kernel module being ~70 larger. Most users
+ will typically not need this high verbosity debug information.

+ This will result in the kernel module being ~70k larger. You
+ can control which debug output is sent to the kernel log by

+
+ /proc/net/ieee80211/debug_level
+
+ For example:
+
+ % echo 0x00000FFO > /proc/net/ieee80211/debug_level
+
+ For a list of values you can assign to debug_level, you
+ can look at the bit mask values in <net/ieee80211.h>

+
+In the event that fragmentation is required, the incoming payload is split into
+N parts of size ieee->fts. The first fragment contains the SNAP header and the
+remaining packets are just data.
+
+If encryption is enabled, each fragment payload size is reduced by enough space
+to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
+So if you have 1500 bytes of payload with ieee->fts set to 500 without
+encryption it will take 3 frames. With WEP it will take 4 frames as the
+payload of each frame is reduced to 492 bytes.
