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

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

97config IWLWIFI_DEBUG
98	bool "Enable full debugging output in the iwlwifi driver"
99	---help---
100	  This option will enable debug tracing output for the iwlwifi drivers
101
102	  This will result in the kernel module being ~100k larger.  You can
103	  control which debug output is sent to the kernel log by setting the
104	  value in
105
106		/sys/module/iwlwifi/parameters/debug
107
108	  This entry will only exist if this option is enabled.
109
110	  To set a value, simply echo an 8-byte hex value to the same file:
111
112		  % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
113
114	  You can find the list of debug mask values in:
115		  drivers/net/wireless/iwlwifi/iwl-debug.h
116
117	  If this is your first time using this driver, you should say Y here
118	  as the debug information can assist others in helping you resolve
119	  any problems you may encounter.

126	  is a low-impact option that allows getting insight into the
127	  driver's state at runtime.

129config IWLWIFI_DEVICE_TRACING
130	bool "iwlwifi device access tracing"
131	depends on EVENT_TRACING
132	default y
133	help
134	  Say Y here to trace all commands, including TX frames and IO
135	  accesses, sent to the device. If you say yes, iwlwifi will
136	  register with the ftrace framework for event tracing and dump
137	  all this information to the ringbuffer, you may need to
138	  increase the ringbuffer size. See the ftrace documentation
139	  for more information.
140
141	  When tracing is not enabled, this option still has some
142	  (though rather small) overhead.
143
144	  If unsure, say Y so we can help you better when problems
145	  occur.
