0018
0019 See <file:Documentation/networking/device_drivers/wifi/intel/ipw2100.rst>
0020 for information on the capabilities currently enabled in this driver
0021 and for tips for debugging issues and problems.
0022
0023 In order to use this driver, you will need a firmware image for it.
0024 You can obtain the firmware from
0025 <http://ipw2100.sf.net/>. Once you have the firmware image, you
0026 will need to place it in /lib/firmware.
0027
0028 You will also very likely need the Wireless Tools in order to
0029 configure your card:

0032
0033 It is recommended that you compile this driver as a module (M)
0034 rather than built-in (Y). This driver requires firmware at device
0035 initialization time, and when built-in this typically happens
0036 before the filesystem is accessible (hence firmware will be
0037 unavailable and initialization will fail). If you do choose to build
0038 this driver into your kernel image, you can avoid this problem by
0039 including the firmware and a firmware loader in an initramfs.

0045 Enables promiscuous/monitor mode support for the ipw2100 driver.
0046 With this feature compiled into the driver, you can switch to
0047 promiscuous mode via the Wireless Tool's Monitor mode. While in this
0048 mode, no packets can be sent.

0056 This will result in the kernel module being ~60k larger. You can
0057 control which debug output is sent to the kernel log by setting the
0058 value in

0062 This entry will only exist if this option is enabled.

0121 Enables the creation of a second interface prefixed 'rtap'.
0122 This second interface will provide every received in radiotap
0123 format.
0124
0125 This is useful for performing wireless network analysis while
0126 maintaining an active association.
0127

0129
0130 % modprobe ipw2200 rtap_iface=1
0131 % ifconfig rtap0 up
0132 % tethereal -i rtap0
0133
0134 If you do not specify 'rtap_iface=1' as a module parameter then
0135 the rtap interface will not be created and you will need to turn
0136 it on via sysfs:

0150 Note, normal debug code is already compiled in. This low level
0151 debug option enables debug on hot paths (e.g Tx, Rx, ISR) and
0152 will result in the kernel module being ~70 larger. Most users
0153 will typically not need this high verbosity debug information.

0181 This will result in the kernel module being ~70k larger. You
0182 can control which debug output is sent to the kernel log by
0183 setting the value in

0188
0189 % echo 0x00000FFO > /proc/net/ieee80211/debug_level
0190
0191 For a list of values you can assign to debug_level, you
0192 can look at the bit mask values in ieee80211.h
