- * WiFi load, scan, associate, unload stress test
- *
- * Repeatedly executes the following sequence:
- *
- *   1. Load WiFi driver
- *   2. Start supplicant
- *   3. Random delay
- *   4. Obtain supplicant status (optional)
- *   5. Stop supplicant
- *   6. Unload WiFi driver
- *
- * The "Obtain supplicant status" step is optional and is pseudo
- * randomly performed 50% of the time.  The default range of
- * delay after start supplicant is intentionally selected such
- * that the obtain supplicant status and stop supplicant steps
- * may be performed while the WiFi driver is still performing a scan
- * or associate.  The default values are given by DEFAULT_DELAY_MIN
- * and DEFAULT_DELAY_MAX.  Other values can be specified through the
- * use of the -d and -D command-line options.
- *
- * Each sequence is refered to as a pass and by default an unlimited
- * number of passes are performed.  An override of the range of passes
- * to be executed is available through the use of the -s (start) and
- * -e (end) command-line options.  Can also specify a single specific
- * pass via the -p option.  There is also a default time in which the
- * test executes, which is given by DEFAULT_DURATION and can be overriden
- * through the use of the -t command-line option.
