16When wake on WiFi is supported and enabled, our system could wake up from
17suspend in dark resume for several reasons. Due to privacy concerns, we do not
18want active scans to be launched on certain types of dark resume wakes where the
19user does not expect information that can uniquely identify their system
20(e.g. MAC addresses) to be broadcasted.
21
22We permit active scans to be launched when the system wakes up due to a SSID
23match or disconnect, since we might try to connect or reconnect to known
24networks during these periods, and the connection/authentication process
25inevitably broadcasts MAC addresses.
26
27However, when the system wakes up due to a RTC timer (e.g. the periodic scan
28timer or DHCP lease renewal timer) or a packet pattern match, we expect the
29system to carry out its tasks and re-suspend without active scanning and
30broadcasting MAC addresses.
31
32This test attempts to verify that no active scans are started in dark resumes
33that are triggered by RTC timers or packet pattern matches. Verify this by
34triggering these wake events and analyzing packet captures to ensure that the
35DUT does not launch any probe requests during these dark resumes.
