Subject: 

We are making a kernel level packet capture module as a part of our BE project .
We are finding it difficult to understand kenel networking code.
We studied structures and functions like sk_buff, netif_rx(),dev_alloc_skb.
How ever we were not able to trace the actual path a simple packet follows.
Moreover we tried to count the no of times netif_rx function was
called it was much much lower than amount of packets actually being
received.
Can anyone please let us know the reason for this and how to approach
the problem of writing a kernel level packet capture module.
