Hi Tao,

Thank you for putting together the python script. I double checked
output of the script and the output of the test and find these
consistent.

(I noticed that a few kfuncs are in the vmlinux.h but are not printed
 by the test:
 - bpf_skb_get_xfrm_info
 - bpf_skb_set_xfrm_info
 - bpf_xdp_get_xfrm_state
 - bpf_xdp_xfrm_state_release
 - bpf_dynptr_from_skb
 - bpf_dynptr_from_xdp
 - bpf_sock_addr_set_sun_path
 but that is another topic).

Thanks,
Eduard
