+# End-to-end eBPF tunnel test suite
+# The script tests BPF network tunnel implementation.
+#
+# Topology:
+# ---------
+# root namespace | at_ns0 namespace
+# |
+# ----------- | -----------
+# | tnl dev | | | tnl dev | (overlay network)
+# ----------- | -----------
+# metadata-mode | native-mode
+# with bpf |
+# |
+# ---------- | ----------
+# | veth1 | --------- | veth0 | (underlay network)
+# ---------- peer ----------
+#
+#
+# Device Configuration
+# --------------------
+# Root namespace with metadata-mode tunnel + BPF
+# Device names and addresses:
+# veth1 IP: 172.16.1.200, IPv6: 00::22 (underlay)
+# tunnel dev <type>11, ex: gre11, IPv4: 10.1.1.200 (overlay)
+#
+# Namespace at_ns0 with native tunnel
+# Device names and addresses:
+# veth0 IPv4: 172.16.1.100, IPv6: 00::11 (underlay)
+# tunnel dev <type>00, ex: gre00, IPv4: 10.1.1.100 (overlay)
+#
+#
+# End-to-end ping packet flow
+# ---------------------------
+# Most of the tests start by namespace creation, device configuration,
+# then ping the underlay and overlay network. When doing 'ping 10.1.1.100'
+# from root namespace, the following operations happen:
+# 1) Route lookup shows 10.1.1.100/24 belongs to tnl dev, fwd to tnl dev.
+# 2) Tnl device's egress BPF program is triggered and set the tunnel metadata,
+# with remote_ip=172.16.1.200 and others.
+# 3) Outer tunnel header is prepended and route the packet to veth1's egress
+# 4) veth0's ingress queue receive the tunneled packet at namespace at_ns0
+# 5) Tunnel protocol handler, ex: vxlan_rcv, decap the packet
+# 6) Forward the packet to the overlay tnl dev
