Nginx 在 FreeBSD 下不支持 reuseport 这个特性的 bug 修了没 ? 求解，我不知道去哪找。

找到了。Nginx 的 changelog 里显示 2018 年把这个 Bug 给修了....

Changes with nginx 1.15.1 03 Jul 2018

*) Feature: the "random" directive inside the "upstream" block.

*) Feature: improved performance when using the "hash" and "ip_hash"
directives with the "zone" directive.

*) Feature: the "reuseport" parameter of the "listen" directive now uses
SO_REUSEPORT_LB on FreeBSD 12.

*) Bugfix: HTTP/2 server push did not work if SSL was terminated by a
proxy server in front of nginx.

*) Bugfix: the "tcp_nopush" directive was always used on backend
connections.

*) Bugfix: sending a disk-buffered request body to a gRPC backend might
fail.

记录一下为后来人排个坑。

截至目前，FreeBSD 13 上 reuseport 模块功能正常，但是没有 ngx_stream_proxy_module 模块，所以 proxy protocol 还没法用。
