[PATCH bpf-next 15/15] selftests/bpf: Use start_server_str in sockmap_helpers

[Geliang Tang <geliang@xxxxxxxxxx>]

From: Geliang Tang <tanggeliang@xxxxxxxxxx>

Now both SOCK_SEQPACKET and SOCK_NONBLOCK can be passed as "type" parameter
into start_server_str(), use this helper in socket_loopback_reuseport() in
sockmap_helpers.h to simplify the code.
