0. Introduction
------------ ----- ----- ---- --- -- -
This document provides a brief overview of the features supported by the
IPW2100 driver project. The main project website, where the latest
development version of the driver can be found, is:
http://ipw2100.sourceforge.net
There you can find the not only the latest releases, but also information about
potential fixes and patches, as well as links to the development mailing list
for the driver project.
===========================
1. Release 1.1.0 Current Supported Features
---------------------------
- Managed (BSS) and Ad-Hoc (IBSS)
- WEP (shared key and open)
- Wireless Tools support
- 802.1x (tested with XSupplicant 1.0.1)
Enabled (but not supported) features:
- Monitor/RFMon mode
- WPA/WPA2
The distinction between officially supported and enabled is a reflection
on the amount of validation and interoperability testing that has been
performed on a given feature.
===========================
2. Command Line Parameters
---------------------------
If the driver is built as a module, the following optional parameters are used
by entering them on the command line with the modprobe command using this
syntax:
modprobe ipw2100 [<option>=<VAL1><,VAL2>...]
For example, to disable the radio on driver loading, enter:
modprobe ipw2100 disable=1
The ipw2100 driver supports the following module parameters:
Name Value Example:
debug 0x0-0xffffffff debug=1024
mode 0,1,2 mode=1 /* AdHoc */
channel int channel=3 /* Only valid in AdHoc or Monitor */
associate boolean associate=0 /* Do NOT auto associate */
disable boolean disable=1 /* Do not power the HW */
===========================
3. Sysfs Helper Files
---------------------------
There are several ways to control the behavior of the driver. Many of the
general capabilities are exposed through the Wireless Tools (iwconfig). There
are a few capabilities that are exposed through entries in the Linux Sysfs.
----- Driver Level ------
For the driver level files, look in /sys/bus/pci/drivers/ipw2100/
debug_level
This controls the same global as the 'debug' module parameter. For
information on the various debugging levels available, run the 'dvals'
script found in the driver source directory.
NOTE: 'debug_level' is only enabled if CONFIG_IPW2100_DEBUG is turn
on.
----- Device Level ------
For the device level files look in
/sys/bus/pci/drivers/ipw2100/{PCI-ID}/
For example:
/sys/bus/pci/drivers/ipw2100/0000:02:01.0
For the device level files, see /sys/bus/pci/drivers/ipw2100:
rf_kill
read -
0 = RF kill not enabled (radio on)
1 = SW based RF kill active (radio off)
2 = HW based RF kill active (radio off)
3 = Both HW and SW RF kill active (radio off)
write -
0 = If SW based RF kill active, turn the radio back on
1 = If radio is on, activate SW based RF kill
NOTE: If you enable the SW based RF kill and then toggle the HW
based RF kill from ON -> OFF -> ON, the radio will NOT come back on
===========================
4. Radio Kill Switch
---------------------------
Most laptops provide the ability for the user to physically disable the radio.
Some vendors have implemented this as a physical switch that requires no
software to turn the radio off and on. On other laptops, however, the switch
is controlled through a button being pressed and a software driver then making
calls to turn the radio off and on. This is referred to as a "software based
RF kill switch"
See the Sysfs helper file 'rf_kill' for determining the state of the RF switch
on your system.
===========================
5. Dynamic Firmware
---------------------------
As the firmware is licensed under a restricted use license, it can not be
included within the kernel sources. To enable the IPW2100 you will need a
firmware image to load into the wireless NIC's processors.
You can obtain these images from <http://ipw2100.sf.net/firmware.php>.
See INSTALL for instructions on installing the firmware.
===========================
6. Power Management
---------------------------
The IPW2100 supports the configuration of the Power Save Protocol
through a private wireless extension interface. The IPW2100 supports
the following different modes:
off No power management. Radio is always on.
on Automatic power management
1-5 Different levels of power management. The higher the
number the greater the power savings, but with an impact to
packet latencies.
Power management works by powering down the radio after a certain
interval of time has passed where no packets are passed through the
radio. Once powered down, the radio remains in that state for a given
period of time. For higher power savings, the interval between last
packet processed to sleep is shorter and the sleep period is longer.
When the radio is asleep, the access point sending data to the station
must buffer packets at the AP until the station wakes up and requests
any buffered packets. If you have an AP that does not correctly support
the PSP protocol you may experience packet loss or very poor performance
while power management is enabled. If this is the case, you will need
to try and find a firmware update for your AP, or disable power
management (via `iwconfig eth1 power off`)
To configure the power level on the IPW2100 you use a combination of
iwconfig and iwpriv. iwconfig is used to turn power management on, off,
and set it to auto.
iwconfig eth1 power off Disables radio power down
iwconfig eth1 power on Enables radio power management to
last set level (defaults to AUTO)
iwpriv eth1 set_power 0 Sets power level to AUTO and enables
power management if not previously
enabled.
iwpriv eth1 set_power 1-5 Set the power level as specified,
enabling power management if not
previously enabled.
You can view the current power level setting via:
iwpriv eth1 get_power
It will return the current period or timeout that is configured as a string
in the form of xxxx/yyyy (z) where xxxx is the timeout interval (amount of
time after packet processing), yyyy is the period to sleep (amount of time to
wait before powering the radio and querying the access point for buffered
packets), and z is the 'power level'. If power management is turned off the
xxxx/yyyy will be replaced with 'off' -- the level reported will be the active
level if `iwconfig eth1 power on` is invoked.
===========================

1. Introduction
-----------------------------------------------
The following sections attempt to provide a brief introduction to using
the Intel(R) PRO/Wireless 2915ABG Driver for Linux.
This document is not meant to be a comprehensive manual on
understanding or using wireless technologies, but should be sufficient
to get you moving without wires on Linux.
For information on building and installing the driver, see the INSTALL
file.
1.1. Overview of Features
-----------------------------------------------
The current release (1.0.0) supports the following features:
+ BSS mode (Infrastructure, Managed)
+ IBSS mode (Ad-Hoc)
+ WEP (OPEN and SHARED KEY mode)
+ 802.1x EAP via wpa_supplicant and xsupplicant
+ Wireless Extension support
+ Full B and G rate support (2200 and 2915)
+ Full A rate support (2915 only)
+ Transmit power control
+ S state support (ACPI suspend/resume)
+ long/short preamble support
1.2. Command Line Parameters
-----------------------------------------------
Like many modules used in the Linux kernel, the Intel(R) PRO/Wireless
2915ABG Driver for Linux allows certain configuration options to be
provided as module parameters. The most common way to specify a module
parameter is via the command line.
The general form is:
% modprobe ipw2200 parameter=value
Where the supported parameter are:
associate
Set to 0 to disable the auto scan-and-associate functionality of the
driver. If disabled, the driver will not attempt to scan
for and associate to a network until it has been configured with
one or more properties for the target network, for example configuring
the network SSID. Default is 1 (auto-associate)
Example: % modprobe ipw2200 associate=0
auto_create
Set to 0 to disable the auto creation of an Ad-Hoc network
matching the channel and network name parameters provided.
Default is 1.
channel
channel number for association. The normal method for setting
the channel would be to use the standard wireless tools
(i.e. `iwconfig eth1 channel 10`), but it is useful sometimes
to set this while debugging. Channel 0 means 'ANY'
debug
If using a debug build, this is used to control the amount of debug
info is logged. See the 'dval' and 'load' script for more info on
how to use this (the dval and load scripts are provided as part
of the ipw2200 development snapshot releases available from the
SourceForge project at http://ipw2200.sf.net)
mode
Can be used to set the default mode of the adapter.
0 = Managed, 1 = Ad-Hoc
1.3. Wireless Extension Private Methods
-----------------------------------------------
As an interface designed to handle generic hardware, there are certain
capabilities not exposed through the normal Wireless Tool interface. As
such, a provision is provided for a driver to declare custom, or
private, methods. The Intel(R) PRO/Wireless 2915ABG Driver for Linux
defines several of these to configure various settings.
The general form of using the private wireless methods is:
% iwpriv $IFNAME method parameters
Where $IFNAME is the interface name the device is registered with
(typically eth1, customized via one of the various network interface
name managers, such as ifrename)
The supported private methods are:
get_mode
Can be used to report out which IEEE mode the driver is
configured to support. Example:
% iwpriv eth1 get_mode
eth1 get_mode:802.11bg (6)
set_mode
Can be used to configure which IEEE mode the driver will
support.
Usage:
% iwpriv eth1 set_mode {mode}
Where {mode} is a number in the range 1-7:
1 802.11a (2915 only)
2 802.11b
3 802.11ab (2915 only)
4 802.11g
5 802.11ag (2915 only)
6 802.11bg
7 802.11abg (2915 only)
get_preamble
Can be used to report configuration of preamble length.
set_preamble
Can be used to set the configuration of preamble length:
Usage:
% iwpriv eth1 set_preamble {mode}
Where {mode} is one of:
1 Long preamble only
0 Auto (long or short based on connection)
1.4. Sysfs Helper Files:
-----------------------------------------------
The Linux kernel provides a pseudo file system that can be used to
access various components of the operating system. The Intel(R)
PRO/Wireless 2915ABG Driver for Linux exposes several configuration
parameters through this mechanism.
An entry in the sysfs can support reading and/or writing. You can
typically query the contents of a sysfs entry through the use of cat,
and can set the contents via echo. For example:
% cat /sys/bus/pci/drivers/ipw2200/debug_level
Will report the current debug level of the driver's logging subsystem
(only available if CONFIG_IPW_DEBUG was configured when the driver was
built).
You can set the debug level via:
% echo $VALUE > /sys/bus/pci/drivers/ipw2200/debug_level
Where $VALUE would be a number in the case of this sysfs entry. The
input to sysfs files does not have to be a number. For example, the
firmware loader used by hotplug utilizes sysfs entries for transferring
the firmware image from user space into the driver.
The Intel(R) PRO/Wireless 2915ABG Driver for Linux exposes sysfs entries
at two levels -- driver level, which apply to all instances of the
driver (in the event that there are more than one device installed) and
device level, which applies only to the single specific instance.
1.4.1 Driver Level Sysfs Helper Files
-----------------------------------------------
For the driver level files, look in /sys/bus/pci/drivers/ipw2200/
debug_level
This controls the same global as the 'debug' module parameter
1.4.2 Device Level Sysfs Helper Files
-----------------------------------------------
For the device level files, look in
/sys/bus/pci/drivers/ipw2200/{PCI-ID}/
For example:
/sys/bus/pci/drivers/ipw2200/0000:02:01.0
For the device level files, see /sys/bus/pci/[drivers/ipw2200:
rf_kill
read -
0 = RF kill not enabled (radio on)
1 = SW based RF kill active (radio off)
2 = HW based RF kill active (radio off)
3 = Both HW and SW RF kill active (radio off)
write -
0 = If SW based RF kill active, turn the radio back on
1 = If radio is on, activate SW based RF kill
NOTE: If you enable the SW based RF kill and then toggle the HW
based RF kill from ON -> OFF -> ON, the radio will NOT come back on
ucode
read-only access to the ucode version number
2. About the Version Numbers
-----------------------------------------------
Due to the nature of open source development projects, there are
frequently changes being incorporated that have not gone through
a complete validation process. These changes are incorporated into
development snapshot releases.
Releases are numbered with a three level scheme:
major.minor.development
Any version where the 'development' portion is 0 (for example
1.0.0, 1.1.0, etc.) indicates a stable version that will be made
available for kernel inclusion.
Any version where the 'development' portion is not a 0 (for
example 1.0.1, 1.1.5, etc.) indicates a development version that is
being made available for testing and cutting edge users. The stability
and functionality of the development releases are not know. We make
efforts to try and keep all snapshots reasonably stable, but due to the
frequency of their release, and the desire to get those releases
available as quickly as possible, unknown anomalies should be expected.
The major version number will be incremented when significant changes
are made to the driver. Currently, there are no major changes planned.

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".

---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/.

---help---
This option will enable debug tracing output for the
ieee80211 network stack.
This will result in the kernel module being ~70k larger. You
can control which debug output is sent to the kernel log by
setting the value in
/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>

(aka TGi, WPA, WPA2, WPA-PSK, etc.) for use with TKIP enabled
networks.
This can be compiled as a modules and it will be called
"ieee80211_crypt_tkip".

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.
