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

 87	bool "Enable full debugging output in the iwlwifi driver"
 88	help
 89	  This option will enable debug tracing output for the iwlwifi drivers
 90
 91	  This will result in the kernel module being ~100k larger.  You can
 92	  control which debug output is sent to the kernel log by setting the
 93	  value in
 94
 95		/sys/module/iwlwifi/parameters/debug
 96
 97	  This entry will only exist if this option is enabled.
 98
 99	  To set a value, simply echo an 8-byte hex value to the same file:
100
101		  % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
102
103	  You can find the list of debug mask values in:
104		  drivers/net/wireless/iwlwifi/iwl-debug.h
105
106	  If this is your first time using this driver, you should say Y here
107	  as the debug information can assist others in helping you resolve
108	  any problems you may encounter.

123	  Say Y here to trace all commands, including TX frames and IO
124	  accesses, sent to the device. If you say yes, iwlwifi will
125	  register with the ftrace framework for event tracing and dump
126	  all this information to the ringbuffer, you may need to
127	  increase the ringbuffer size. See the ftrace documentation
128	  for more information.
129
130	  When tracing is not enabled, this option still has some
131	  (though rather small) overhead.
132

134	  occur.

147
148	  CSME stands for Converged Security and Management Engine. It is a CPU
149	  on the chipset and runs a dedicated firmware. AMT (Active Management
150	  Technology) is one of the applications that run on that CPU. AMT
151	  allows to control the platform remotely.
152
153	  This kernel module allows to communicate with the Intel Management
154	  Engine over Wifi. This is supported starting from Tiger Lake
155	  platforms and has been tested on 9260 devices only.
156	  If AMT is configured not to use the wireless device, this module is
157	  harmless (and useless).
158	  Enabling this option on a platform that has a different device and
159	  has Wireless enabled on AMT can prevent WiFi from working correctly.
