  Modified files:
    sys/boot/forth       loader.conf 
    sys/netgraph         ng_base.c 
  Log:
  Add two loader tuneables that allow one to change the maximum number of
  queue items that can be allocated by netgraph and the number of free queue
  items that are cached on a private list.
  
  Netgraph places an upper limit on the number of queue items it may allocate.
  When there is a large number of netgraph messages travelling through the
  system (100k/sec and more) there is a high probability, that messages get
  queued at the nodes and netgraph runs out of queue items. In this case the data
  flow through netgraph gets blocked. The tuneable for the number of free
  items lets one trade memory for performance.
  
  The tunables are also available as read-only sysctls.
