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.

113e705c121SKalle Valo
114e705c121SKalle Valo	  This will result in the kernel module being ~100k larger.  You can
115e705c121SKalle Valo	  control which debug output is sent to the kernel log by setting the

121e705c121SKalle Valo
122e705c121SKalle Valo	  To set a value, simply echo an 8-byte hex value to the same file:
123e705c121SKalle Valo
124e705c121SKalle Valo		  % echo 0x43fff > /sys/module/iwlwifi/parameters/debug

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

148e705c121SKalle Valo	  register with the ftrace framework for event tracing and dump
149e705c121SKalle Valo	  all this information to the ringbuffer, you may need to
150e705c121SKalle Valo	  increase the ringbuffer size. See the ftrace documentation
151e705c121SKalle Valo	  for more information.
152e705c121SKalle Valo
