From: Geliang Tang <[e-mail]>

v3:
 - patch 2:
   - clear errno before connect_to_fd_opts.
   - print err logs in run_test.
   - set err to -1 when fd >= 0.
 - patch 3:
   - drop "int err".

v2:
 - update patch 2 as Martin suggested.

This is the 9th part of series "use network helpers" all BPF selftests
wide.

Patches 1-2 update network helpers interfaces suggested by Martin.
Patch 3 adds a new helper connect_to_addr_str() as Martin suggested
instead of adding connect_fd_to_addr_str().
Patch 4 uses this newly added helper in make_client().
Patch 5 uses make_client() in sk_lookup and drop make_socket().

Geliang Tang (5):
  selftests/bpf: Drop type of connect_to_fd_opts
  selftests/bpf: Drop must_fail from network_helper_opts
  selftests/bpf: Add connect_to_addr_str helper
  selftests/bpf: Use connect_to_addr_str in sk_lookup
  selftests/bpf: Drop make_socket in sk_lookup
