*
* This l2_packet implementation is explicitly for WinPcap and Windows events.
* l2_packet_pcap.c has support for WinPcap, but it requires polling to receive
* frames which means relatively long latency for EAPOL RX processing. The
* implementation here uses a separate thread to allow WinPcap to be receiving
* all the time to reduce latency for EAPOL receiving from about 100 ms to 3 ms
* when comparing l2_packet_pcap.c to l2_packet_winpcap.c. Extra sleep of 50 ms
* is added in to receive thread whenever no EAPOL frames has been received for
* a while. Whenever an EAPOL handshake is expected, this sleep is removed.
*
* The RX thread receives a frame and signals main thread through Windows event
* about the availability of a new frame. Processing the received frame is
* synchronized with pair of Windows events so that no extra buffer or queuing
* mechanism is needed. This implementation requires Windows specific event
* loop implementation, i.e., eloop_win.c.
*
* WinPcap has pcap_getevent() that could, in theory at least, be used to
* implement this kind of waiting with a simpler single-thread design. However,
* that event handle is not really signaled immediately when receiving each
* frame, so it does not really work for this kind of use.
