X-Header
This feature supports the X-Header capture in slowpath PCAP. When UPF inserts the X-Header for Uplink packet, the UPF captures the packet at entry and exit interfaces. So, the exit packet sent to N6 contains the inserted X-header.
When UPF inserts the X-header for Downlink packet, the UPF captures the packet at entry and exit interfaces. So, the exit packet sent to N3 contains the inserted x-header.
