I'm working on https://reviews.freebsd.org/D39638 (sysctl(9): Enable = vnet sysctl variables be loader tunable) and I think it is new feature, but not quite sure whether the KBI = changed. So, 1. Is it a KBI change ? 2. It is a simple change ( while so far as I know currently only tested = by myself on x86 and qemu riscv ), can it catch up with 14 ? Best regards, Zhenlei
