# This is designed to test that the connection manager is able to scan
# and connect to a configured network after resume-from-suspend
# even if we were not connected at the time we went into suspend.
# To accomplish this, we join an AP (so we are sure that flimflam
# remembers it), then turn off the AP and wait for the service to
# disappear.  We suspend the DUT, re-instate the AP, then resume,
# so that when the device awakes, the AP is in full view.  We then
# wait for the DUT to re-connect.
