Currently it's enabled by option https://docs.haproxy.org/3.0/configuration.html#4.2-option splice-auto and AFAICT requires https://github.com/haproxy/haproxy/blob/master/Makefile#L30 preset in https://github.com/haproxy/haproxy/blob/master/Makefile#L416 > The code review is here if anyone's interested in looking at the > implementation: https://reviews.freebsd.org/D46411 A+ Dave
