My extension check routine is called on every iptables command

G'day !

I have back ported Port Trigger for kernel 2.6.18 iptables 1.4.9


I had a debug print to trace function invocation and I had noticed a strange effect
 on every iptaple command the trigger_check() ( registered as .checkentry=trigger_check ) from the kernel extension is invoked and prints a tracing  message

I wonder how it may happen, it seems that iptables scans the whole tree of netfilter structures ?  


ThanX
