"Linux Device Drivers" The 17th Chapter Network Driver--note

Brief introduction The network interface is the third class of standard Linux devices, and this chapter describes how the network interface interacts with the rest of the kernel. The network interface must register itself with a specific kernel data structure in case it is called when the packet is exchanged with the outside world. There is

If the routing table for the two routers is complete, the package will answer successfully. If the first router does not have a static route configured, only RIPis configured, and if there are two
