The libpfctl port fix should land soon, but I figured that it’d be better to keep the definitions, because userspace doesn’t know if the kernel is built with or without COMPAT_FREEBSD14. I’m open to being persuaded that that’s a bad idea though. Long-term (i.e. by freebsd 16) the plan is for all of these ioctls to go away (so the code for them will stay in 15, but not be in 16), but that does depend on me doing a fair bit of work before then.
