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

  85           Say Y here to enable default bcast filtering configuration.
  86
  87           Enabling broadcast filtering will drop any incoming wireless
  88           broadcast frames, except some very specific predefined
  89           patterns (e.g. incoming arp requests).
  90
  91           If unsure, don't enable this option, as some programs might
  92           expect incoming broadcasts for their normal operations.

  98          Say Y here to enable runtime power management for PCIe
  99          devices.  If enabled, the device will go into low power mode
 100          when idle for a short period of time, allowing for improved
 101          power saving during runtime. Note that this feature requires
 102          a tight integration with the platform. It is not recommended
 103          to enable this feature without proper validation with the
 104          specific target platform.

 111         bool "Enable full debugging output in the iwlwifi driver"
 112         ---help---
 113           This option will enable debug tracing output for the iwlwifi drivers
 114
 115           This will result in the kernel module being ~100k larger.  You can
 116           control which debug output is sent to the kernel log by setting the
 117           value in
 118
 119                 /sys/module/iwlwifi/parameters/debug
 120
 121           This entry will only exist if this option is enabled.
 122
 123           To set a value, simply echo an 8-byte hex value to the same file:
 124
 125                   % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
 126
 127           You can find the list of debug mask values in:
 128                   drivers/net/wireless/iwlwifi/iwl-debug.h
 129
 130           If this is your first time using this driver, you should say Y here
 131           as the debug information can assist others in helping you resolve
 132           any problems you may encounter.

 138           Enable creation of debugfs files for the iwlwifi drivers. This
 139           is a low-impact option that allows getting insight into the
 140           driver's state at runtime.

 146         help
 147           Say Y here to trace all commands, including TX frames and IO
 148           accesses, sent to the device. If you say yes, iwlwifi will
 149           register with the ftrace framework for event tracing and dump
 150           all this information to the ringbuffer, you may need to
 151           increase the ringbuffer size. See the ftrace documentation
 152           for more information.
 153
 154           When tracing is not enabled, this option still has some
 155           (though rather small) overhead.
 156
 157           If unsure, say Y so we can help you better when problems
 158           occur.
