if_set_bpf_tap

Hi..

Has anyone managed to use the if_set_bpf_tap function documented in
Network Kernel Extension ?

Here is what I got when i try to load a network kext i'm developping.
(I'm on OSX 10.1.3)

[g4:~sam/OSX-PF] root# more OSX_PF.c
#include <gen.h>
#include <sys/systm.h>
#include <mach/mach_types.h>

kern_return_t OSX_PF_start (kmod_info_t * ki, void * d)
{
int test;

printf("Module has loaded!\n");
test = 0;
if_set_bpf_tap(test,test,test);
return KERN_SUCCESS;
}

kern_return_t OSX_PF_stop (kmod_info_t * ki, void * d)
{
printf("Module will be unloaded\n");
return KERN_SUCCESS;
}

[g4:~sam/OSX-PF] root# kextload build/OSX-PF.kext
kmodload: kld(): kmodload: Undefined symbols:kmodload:
kmodload: _if_set_bpf_tap
kmodload: kld_load() failed.Error loading module: kmod load error.
[g4:~sam/OSX-PF] root#

Thanx for any help.
