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

  80           Say Y here to enable default bcast filtering configuration.
  81
  82           Enabling broadcast filtering will drop any incoming wireless
  83           broadcast frames, except some very specific predefined
  84           patterns (e.g. incoming arp requests).
  85
  86           If unsure, don't enable this option, as some programs might
  87           expect incoming broadcasts for their normal operations.

  93           Say Y here to enable U-APSD by default. This may cause
  94           interoperability problems with some APs, manifesting in lower than
  95           expected throughput due to those APs not enabling aggregation

 102         bool "Enable full debugging output in the iwlwifi driver"
 103         ---help---
 104           This option will enable debug tracing output for the iwlwifi drivers
 105
 106           This will result in the kernel module being ~100k larger.  You can
 107           control which debug output is sent to the kernel log by setting the
 108           value in
 109
 110                 /sys/module/iwlwifi/parameters/debug
 111
 112           This entry will only exist if this option is enabled.
 113
 114           To set a value, simply echo an 8-byte hex value to the same file:
 115
 116                   % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
 117
 118           You can find the list of debug mask values in:
 119                   drivers/net/wireless/iwlwifi/iwl-debug.h
 120
 121           If this is your first time using this driver, you should say Y here
 122           as the debug information can assist others in helping you resolve
 123           any problems you may encounter.

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

 134         bool "Experimental uCode support"

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