try to run 7.1 ifconfig on 8.0. without COMPAT_70 in the kernel, it won't run. Its non-compatibility is probably buried deep within a switch statement for a generic function. The only way we can reasonably make it work is: - lie about what compat is, and build it inot the kernel, which also hurts people who want to remove it because they are using weak archs - make networking modular? - kernel hot patching (runtime cost) We can drop the pretense. it doesn't work. !DSPAM:59979908113027780614962!
