Similar to gre, vxlan, geneve, ipip tunnels, allow ip6gretap tunnels to
operate in collect metadata mode.  The first patch adds the support to
ip6_gre.c. The second patch enables unsetting the csum for ipv6 tunnel,
when using bpf_skb_[gs]et_tunnel_key() helpers.  Finally, the last patch
adds the ip6 gre and gretap tunnel test cases to BPF sample code.

The corresponding iproute2 patch:

William Tu (3):
  ip6_gre: add ip6 gre and gretap collect_md mode
  bpf: allow disabling tunnel csum for ipv6
  samples/bpf: extend test_tunnel_bpf.sh with ip6gre
