Bläddra i källkod 
Add support for prog types that were added to kernel but not present in
bpftool yet: struct_ops, tracing, ext prog types and corresponding
section names.

Before:
  # bpftool p l
  ...
  184: type 26  name test_subprog3  tag dda135a7dc0daf54  gpl
          loaded_at 2020-02-25T13:28:33-0800  uid 0
          xlated 112B  jited 103B  memlock 4096B  map_ids 136
          btf_id 85
  185: type 28  name new_get_skb_len  tag d2de5b87d8e5dc49  gpl
          loaded_at 2020-02-25T13:28:33-0800  uid 0
          xlated 72B  jited 69B  memlock 4096B  map_ids 136
          btf_id 85

After:
  # bpftool p l
  ...
  184: tracing  name test_subprog3  tag dda135a7dc0daf54  gpl
          loaded_at 2020-02-25T13:28:33-0800  uid 0
          xlated 112B  jited 103B  memlock 4096B  map_ids 136
          btf_id 85
  185: ext  name new_get_skb_len  tag d2de5b87d8e5dc49  gpl
          loaded_at 2020-02-25T13:28:33-0800  uid 0
          xlated 72B  jited 69B  memlock 4096B  map_ids 136
          btf_id 85
