Query regarding netfilter hooks

Hi,

I have a basic query regarding netfilter hooks on Unix platforms.
(prerouting, postrouting.. etc)
I am assuming that hooks should be asynchronous.. (there should be
multiple kernel threads handling the call for hook for a packet).

Please correct me if i am wrong..

if they are asynchronous.. where can i find the number of threads
(configuration) for handling this task..

What would be a good reference where i can get such implementation
details about netfilter hooks.

Regards
Sanjay Raghani

I am sure you must be knowing this by now... but just in case you
missed out on that,
there is a pretty detailed website on netfilter/iptables :

Hope this helps
