WifiSyslogUDP

This repo contains updated Wifi UDP traffic logs. An UDP flow pair is identified when the first UDP segment is observed for a UDP socket pair, and is ended when no packet has been observed (from both sides) for 10s after the first packet or 3min after the last data packet. For detailed description, please refer to official documentation.
