I'm not sure I fully understand this, but it seems that these channels are used when there is a socket to the user space, i.e. an application running on the host sends/receives data to/from the network. But what about the case when there's no application? As far as I know, in routers the IP packets usually don't get to user space, but if protocol processing is moved to user space (netfilter), it might degrade performance, mightn't it?
