  Modified files:
    sys/netgraph/netflow ng_netflow.c 
  Log:
  Refactor node so that it does not modify mbuf contents. Next step would
  be pass-thru mode, when traffic is not copied by ng_tee, but passed thru
  ng_netflow.
  
  Changes made:
  
  - In ng_netflow_rcvdata() do all necessary pulluping: Ethernet header,
    IP header, and TCP/UDP header.
  - Pass only pointer to struct ip to ng_netflow_flow_add(). Any TCP/UDP
    headers are guaranteed to by after it.
  - Merge make_flow_rec() function into ng_netflow_flow_add().
