It takes some time for hostapd to complete AP startup. In some cases, this could potentially result in station starting a scan before the AP is beaconing or ready to reply to probes. To avoid such race conditions, wait for AP-ENABLED before going ahead with the test cases. Signed-hostap: Jouni Malinen <j@w1.fi>
