From: Geliang Tang <[e-mail]>

v3:
 - add two more patches.
 - use log_err instead of ASSERT in v3.
 - let send_recv_data return int as Martin suggested.

v2:

Address Martin's comments for v1 (thanks.)
 - drop patch 1, "export send_byte helper".
 - drop "WRITE_ONCE(arg.stop, 0)".
 - rebased.

send_recv_data will be re-used in MPTCP bpf tests, but not included
in this set because it depends on other patches that have not been
in the bpf-next yet. It will be sent as another set soon.

Geliang Tang (4):
  selftests/bpf: Use log_err in network_helpers
  selftests/bpf: Add struct send_recv_arg
  selftests/bpf: Export send_recv_data helper
  selftests/bpf: Support nonblock for send_recv_data
