The test creates two netns, ns1 and ns2. The host (the default netns)
has an ipip or ip6tnl dev configured for tunneling traffic to the ns2.
ping VIPS from ns1 <----> host <--tunnel--> ns2 (VIPs at loopback)
The test is to have ns1 pinging VIPs configured at the loopback
interface in ns2.
The VIPs are 10.10.1.102 and 2401:face::66 (which are configured
at lo@ns2). [Note: 0x66 => 102].
At ns1, the VIPs are routed _via_ the host.
At the host, bpf programs are installed at the veth to redirect packets
from a veth to the ipip/ip6tnl. The test is configured in a way so
that both ingress and egress can be tested.
At ns2, the ipip/ip6tnl dev is configured with the local and remote address
specified. The return path is routed to the dev ipip/ip6tnl.
During egress test, the host also locally tests pinging the VIPs to ensure
that bpf_redirect at egress also works for the direct egress (i.e. not
forwarding from dev ve1 to ve2).
