Merge branch 'ipv6-gre-collect_md'
William Tu says:
====================
add ip6 gre and gretap collect_md mode
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:
