This document outlines the process flow for receiving a packet on a network interface, passing it through various networking stacks in the kernel, and delivering it to a socket or application. Key steps include: 1) The packet is received by the network interface driver and passed to netif_receive_skb. 2) It then goes through processing such as checksum verification, filtering by iptables, and defragmentation if needed. 3) The packet is then routed and delivered to the appropriate socket using functions like ip_local_deliver. 4) Data from the packet is then placed into the receive queue for the socket's application to read.
