Subject: [PATCH net-next 0/4] ip_tunnel: add collect_md mode to IPv4/IPv6 tunnels

Similar to geneve, vxlan, gre tunnels implement 'collect metadata' mode
in ipip, ipip6, ip6ip6 tunnels.

Alexei Starovoitov (4):
  ip_tunnel: add collect_md mode to IPIP tunnel
  ip6_tunnel: add collect_md mode to IPv6 tunnels
  samples/bpf: extend test_tunnel_bpf.sh with IPIP test
  samples/bpf: add comprehensive ipip, ipip6, ip6ip6 test
