annotate src/os/win32/ngx_wsasend.c @ 8816:7ea585a6ed0f quic
QUIC: set to standard TLS codepoint after draft versions removal.
This is to ease transition with oldish BoringSSL versions,
the default for SSL_set_quic_use_legacy_codepoint() has been
flipped in BoringSSL a1d3bfb64fd7ef2cb178b5b515522ffd75d7b8c5.
