Subject: [PATCH bpf-next 1/2] selftest/bpf: add missed ip6ip6 test back
In comment 173ca26e9b51 ("samples/bpf: add comprehensive ipip, ipip6,
ip6ip6 test") we added ip6ip6 test for bpf tunnel testing. But in commit
933a741e3b82 ("selftests/bpf: bpf tunnel test.") when we moved it to
the current folder, we didn't add it.
This patch add the ip6ip6 test back to bpf tunnel test. Since the
underlay network is the same, we can reuse the ipip6 framework directly.
Iperf test is removed as currect framework simplified it in purpose.
