Some quick links, more notes to come later:

"The journey of a packet through the linux 2.4 network stack":

     http://ftp.gnumonks.org/pub/doc/packet-journey-2.4.html

(outlines the architecture of the network stack by example, together
  with 

     http://ftp.gnumonks.org/pub/doc/skb-doc.html

  which explains the socket buffering data structures involved.)


BPF paper, a significant stepping stone in this kind of design:
