See Bug [258679](https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=258679)

L;DR: The v92 port was the first version that had the sendfile optimization on (Free)BSD.
However, the modification was broken for any arch where ssize_t != off_t. 
This got fixed with the v94 port. I really wonder if activating sendfile() was a sensible decision though.
Contrary to Linux the FreeBSD sendfile call limits the out descriptor to a socket. According to the Linux man page the out descriptor can be any file there.
