37 * This program simulates the behavior of the ndis_events utility
38 * supplied with wpa_supplicant for Windows. The original utility
39 * is designed to translate Windows WMI events. We don't have WMI,
40 * but we need to supply certain event info to wpa_supplicant in
41 * order to make WPA2 work correctly, so we fake up the interface.
