4  * End-to-end eBPF tunnel test suite
5  *   The file tests BPF network tunnel implementation.
24  *  root namespace with metadata-mode tunnel + BPF
28  *	tunnel dev <type>11, ex: gre11, IPv4: 10.1.1.200, IPv6: 1::22 (overlay)
30  *  Namespace at_ns0 with native tunnel
33  *	tunnel dev <type>00, ex: gre00, IPv4: 10.1.1.100, IPv6: 1::11 (overlay)
42  *  2) Tnl device's egress BPF program is triggered and set the tunnel metadata,
44  *     the primary or secondary ip of veth1 as the local ip of tunnel. The
46  *  3) Outer tunnel header is prepended and route the packet to veth1's egress.
48  *  5) Tunnel protocol handler, ex: vxlan_rcv, decap the packet.
