Hi John,

here is some preliminary feedback:

* I notice that the parse graph code isn't present yet.
  I suppose this is a difficult piece that naturally follows many
  other piece. None the less it is possibly the piece of most
  interest to me :-)

* Will del and update flows require flows to already exist?
  And similarly, will add flow require flows with the same match to not
  already exist?  If so, the error handling seems tricky of more than one
  flow is to be deleted/updated. IIRC there was some discussion of that
  kind of issue at the (double) round table discussion on the last day of
  LPC14 in Düsseldorf.

* Should the .node_count value of ixgbe_table_node_l2 be 3?
  ixgbe_table_graph_nodes has three elements but perhaps you
  are intentionally excluding the last element ixgbe_table_node_nil?
