Subject: [PATCH bpf-next 0/3] selftests/bpf: small improvements on
 tc_tunnel

Hello,
this series is a small follow-up to the test_tc_tunnel recent
integration, to address some small missing details raised during the
final review ([1]). This is mostly about adding some missing checks on
net namespaces management.

Alexis Lothoré (eBPF Foundation) (3):
      selftests/bpf: skip tc_tunnel subtest if its setup fails
      selftests/bpf: add checks in tc_tunnel when entering net namespaces
      selftests/bpf: use start_server_str rather than start_reuseport_server in tc_tunnel
