Commit Message

Yonghong Song June 23, 2020, 12:36 a.m. UTC 
Added tcp{4,6} and udp{4,6} bpf programs into test_progs
selftest so that they at least can load successfully.
  $ ./test_progs -n 3
  ...
  #3/7 tcp4:OK
  #3/8 tcp6:OK
  #3/9 udp4:OK
  #3/10 udp6:OK
  ...
  #3 bpf_iter:OK
  Summary: 1/16 PASSED, 0 SKIPPED, 0 FAILED
