But I would really like to make it work on RELENG_4. In fact, if bpf.h was not included in if_gif.c, I would not mind. But although I'm not (yet ;p) a kernel hacker, I read quickly bpf(9) manpage and I really think the code should work. I dread that this is due to some back magic I can't even imagine. That's why I made a call here for testimonies or explanations. Thanks. Regards, -- Jeremie Le Hen jeremie@le-hen.org
