Detailed Description

GTP-U Configuration Information.

Due to the LUT2 engine using 32-bit matching parameter, the default GTP-U classification is solely based on its 32-bit tunnel ID. However, it is desirable to match the GTP-U tunnel with both tunnel ID and previous link information. This configuration can be used to modify GTP-U classification vector by combining least significant 24-bit of tunnel ID and an 8-bit previous link. It should be passed to Pa_control() API at system startup.

Note:
GTP-U configuration should be performed at system startup. PASS does not support GTP-U reconfiguration at run time.
This configuration is used at the first generation of PASS and it is still supported by the second generation PASS for backward compatibility only. It does not have real effect since the advanced LUT2 engine supports GTPU 32-bit Tunnel-ID classification with L3 link. It is not necessary to restrict the effective tunnel-ID to 24-bit.
