[PATCH bpf-next 0/2] selftests/bpf: enfoce SO_REUSEADDR in basic test servers

["Alexis Lothoré (eBPF Foundation)" <alexis.lothore@bootlin.com>]

Hello,
This small series is another follow-up to [1], in which I misunderstood
Martin's initial feedback (see [2]). I proposed to make tc-tunnel apply
SO_REUSEPORT once server is brought up. This series updates
start_server_addr to really apply Martin's proposal after his
clarification [3]

Alexis Lothoré (eBPF Foundation) (2):
      selftests/bpf: systematically add SO_REUSEADDR in start_server_addr
      selftests/bpf: use start_server_str rather than start_reuseport_server in tc_tunnel
