The patch migrates the original tests at samples/bpf/tcbpf2_kern.c
and samples/bpf/test_tunnel_bpf.sh to selftests. There are a couple
changes from the original:
1) add ipv6 vxlan, ipv6 geneve, ipv6 ipip tests
2) simplify the original ipip tests (remove iperf tests)
3) improve documentation
4) use bpf_ntoh* and bpf_hton* api
In summary, 'test_tunnel_kern.o' contains the following bpf program:
GRE: gre_set_tunnel, gre_get_tunnel
IP6GRE: ip6gretap_set_tunnel, ip6gretap_get_tunnel
ERSPAN: erspan_set_tunnel, erspan_get_tunnel
IP6ERSPAN: ip4ip6erspan_set_tunnel, ip4ip6erspan_get_tunnel
VXLAN: vxlan_set_tunnel, vxlan_get_tunnel
IP6VXLAN: ip6vxlan_set_tunnel, ip6vxlan_get_tunnel
GENEVE: geneve_set_tunnel, geneve_get_tunnel
IP6GENEVE: ip6geneve_set_tunnel, ip6geneve_get_tunnel
IPIP: ipip_set_tunnel, ipip_get_tunnel
IP6IP: ipip6_set_tunnel, ipip6_get_tunnel,
ip6ip6_set_tunnel, ip6ip6_get_tunnel
XFRM: xfrm_get_state
