  12           Intel Wireless WiFi Link Next-Gen AGN
  13
  14           This option enables support for use with the following hardware:
  15                 Intel Wireless WiFi Link 6250AGN Adapter
  16                 Intel 6000 Series Wi-Fi Adapters (6200AGN and 6300AGN)

  27           This driver uses the kernel's mac80211 subsystem.
  28
  29           In order to use this driver, you will need a microcode (uCode)
  30           image for it. You can obtain the microcode from:
  31
  32                   <http://intellinuxwireless.org/>.
  33
  34           The microcode is typically installed in /lib/firmware. You can
  35           look in the hotplug script /etc/hotplug/firmware.agent to
  36           determine which directory FIRMWARE_DIR is set to when the script
  37           runs.
  38
  39           If you want to compile the driver as a module ( = code which can be
  40           inserted in and removed from the running kernel whenever you want),
  41           say M here and read <file:Documentation/kbuild/modules.txt>.  The
  42           module will be called iwlwifi.

  76         ---help---
  77           This option will enable debug tracing output for the iwlwifi drivers
  78
  79           This will result in the kernel module being ~100k larger.  You can
  80           control which debug output is sent to the kernel log by setting the
  81           value in
  82
  83                 /sys/module/iwlwifi/parameters/debug
  84
  85           This entry will only exist if this option is enabled.
  86
  87           To set a value, simply echo an 8-byte hex value to the same file:
  88
  89                   % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
  90
  91           You can find the list of debug mask values in:
  92                   drivers/net/wireless/iwlwifi/iwl-debug.h
  93
  94           If this is your first time using this driver, you should say Y here
  95           as the debug information can assist others in helping you resolve
  96           any problems you may encounter.

 102           Enable creation of debugfs files for the iwlwifi drivers. This
 103           is a low-impact option that allows getting insight into the

 117           Say Y here to trace all commands, including TX frames and IO
 118           accesses, sent to the device. If you say yes, iwlwifi will
 119           register with the ftrace framework for event tracing and dump
 120           all this information to the ringbuffer, you may need to
 121           increase the ringbuffer size. See the ftrace documentation
 122           for more information.
 123
 124           When tracing is not enabled, this option still has some
 125           (though rather small) overhead.
 126
 127           If unsure, say Y so we can help you better when problems
 128           occur.

 134         depends on IWLWIFI
 135         help
 136           This option enables experimental P2P support for some devices
 137           based on microcode support. Since P2P support is still under
 138           development, this option may even enable it for some devices
 139           now that turn out to not support it in the future due to
 140           microcode restrictions.
 141
 142           To determine if your microcode supports the experimental P2P
 143           offered by this option, check if the driver advertises AP
 144           support when it is loaded.
 145
 146           Say Y only if you want to experiment with P2P.
