Each netchannel, which goes to a specific socket, has a ring
buffer of packets the NIC can use. Those packets are mmap()'d
into userspace so we can control the layout, the page boundaries,
etc. and the NIC will only DMA packets matching that channel ID
into that userland area.
Have a look at the code Kelly posted.
