    sys/net              bridge.c bridge.h if_ethersubr.c 
    sys/netinet          ip_dummynet.c ip_dummynet.h ip_fw.c

  Log:
  Assorted bridge+ipfw+dummynet fixes.  The general goal of this set
  of patches is to reduce the number of places where shared mbuf
  clusters are modified.
  
  In detail:
  ip_fw.c:
      modified the ip_fw_chk interface (so that it does not consume
      the buffer unless strictly necessary).
  
  ip_input.c, ip_output.c, bridge.c:
      reflect above changes.
  
  if_ethersubr.c:
      avoid dereferencing pointers to an mbuf chain after it has been
      freed. Also fix some bugs when interfaces are not part of
      a bridging cluster.
  
  ip_dummynet.[ch]
      largely simplified the WF2Q+ implementation removing a redundant
      data structrure.
  
  bridge.[ch]
      fix the forwarding loop to avoid modifying the packet when
      possible.
