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