Listening mode and syslog identity information

Support for Listening mode and syslog identity information: GTP listening mode This enables GPRS tunneling protocol (GTP) listening mode on the S5, S8, or S11 interface. In listening mode, the firewall can perform sanity check and stateful inspection on GTP packets per GTP configuration. To configure, include the listening-mode statement at the [edit security gtp profile profile-name] hierarchy level. Syslog identity information This feature adds information such as the user equipment (UE) IP address, International Mobile Station Identity (IMSI), and access point name (APN) to existing syslog messages during GTP management. This helps in mapping identities between a user ID and an IP address.
