28e705c121SKalle Valo	  This driver uses the kernel's mac80211 subsystem.
29e705c121SKalle Valo
30e705c121SKalle Valo	  In order to use this driver, you will need a firmware
31e705c121SKalle Valo	  image for it. You can obtain the microcode from:
32e705c121SKalle Valo
33e705c121SKalle Valo	          <http://wireless.kernel.org/en/users/Drivers/iwlwifi>.
34e705c121SKalle Valo
35e705c121SKalle Valo	  The firmware is typically installed in /lib/firmware. You can
36e705c121SKalle Valo	  look in the hotplug script /etc/hotplug/firmware.agent to
37e705c121SKalle Valo	  determine which directory FIRMWARE_DIR is set to when the script
38e705c121SKalle Valo	  runs.
39e705c121SKalle Valo
40e705c121SKalle Valo	  If you want to compile the driver as a module ( = code which can be
41e705c121SKalle Valo	  inserted in and removed from the running kernel whenever you want),
42e705c121SKalle Valo	  say M here and read <file:Documentation/kbuild/modules.txt>.  The
43e705c121SKalle Valo	  module will be called iwlwifi.

112e705c121SKalle Valo
113e705c121SKalle Valo	  This will result in the kernel module being ~100k larger.  You can
114e705c121SKalle Valo	  control which debug output is sent to the kernel log by setting the

120e705c121SKalle Valo
121e705c121SKalle Valo	  To set a value, simply echo an 8-byte hex value to the same file:
122e705c121SKalle Valo
123e705c121SKalle Valo		  % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
124e705c121SKalle Valo
125e705c121SKalle Valo	  You can find the list of debug mask values in:

127e705c121SKalle Valo
128e705c121SKalle Valo	  If this is your first time using this driver, you should say Y here
129e705c121SKalle Valo	  as the debug information can assist others in helping you resolve
130e705c121SKalle Valo	  any problems you may encounter.

146e705c121SKalle Valo	  accesses, sent to the device. If you say yes, iwlwifi will
147e705c121SKalle Valo	  register with the ftrace framework for event tracing and dump
148e705c121SKalle Valo	  all this information to the ringbuffer, you may need to
149e705c121SKalle Valo	  increase the ringbuffer size. See the ftrace documentation
150e705c121SKalle Valo	  for more information.
151e705c121SKalle Valo
152e705c121SKalle Valo	  When tracing is not enabled, this option still has some
153e705c121SKalle Valo	  (though rather small) overhead.
