- Added support for the N9 For Roaming interface type:
- Core interface act as V-UPF.
- Access interface act as H-UPF.
- Modified V-UPF behavior:
- V-UPF updates only the TEID and IP Address in the GTP-U header.
- The content following the Extension Header is passed through directly
between the UE and H-UPF.
This implementation ensures seamless data flow between the UE, V-UPF, and H-UPF
while maintaining integrity for Home Routed Roaming scenarios.
