  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.

  82           Say Y here to enable default bcast filtering configuration.
  83
  84           Enabling broadcast filtering will drop any incoming wireless
  85           broadcast frames, except some very specific predefined
  86           patterns (e.g. incoming arp requests).
  87
  88           If unsure, don't enable this option, as some programs might
  89           expect incoming broadcasts for their normal operations.

  95           Say Y here to enable U-APSD by default. This may cause
  96           interoperability problems with some APs, manifesting in lower than

 117         ---help---
 118           This option will enable debug tracing output for the iwlwifi drivers
 119
 120           This will result in the kernel module being ~100k larger.  You can
 121           control which debug output is sent to the kernel log by setting the
 122           value in
 123
 124                 /sys/module/iwlwifi/parameters/debug
 125
 126           This entry will only exist if this option is enabled.
 127
 128           To set a value, simply echo an 8-byte hex value to the same file:
 129
 130                   % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
 131
 132           You can find the list of debug mask values in:
 133                   drivers/net/wireless/iwlwifi/iwl-debug.h
 134
 135           If this is your first time using this driver, you should say Y here
 136           as the debug information can assist others in helping you resolve
 137           any problems you may encounter.

 157         help
 158           Say Y here to trace all commands, including TX frames and IO
 159           accesses, sent to the device. If you say yes, iwlwifi will
 160           register with the ftrace framework for event tracing and dump
 161           all this information to the ringbuffer, you may need to
 162           increase the ringbuffer size. See the ftrace documentation
 163           for more information.
 164
 165           When tracing is not enabled, this option still has some
 166           (though rather small) overhead.
 167
 168           If unsure, say Y so we can help you better when problems
 169           occur.
