Needs also tooling header copy, but once that is done, it needs fixup for 
libbpf:

[root@pc-9 bpf]# make
  GEN      bpf_helper_defs.h
Unrecognized type 'struct xdp_md', please add it to known types!
make[1]: *** [Makefile:186: bpf_helper_defs.h] Error 1
make[1]: *** Deleting file 'bpf_helper_defs.h'
make: *** [Makefile:160: all] Error 2
[root@pc-9 bpf]#

Daniel
