  Modified files:        (Branch: RELENG_4)
    sys/netgraph         ng_base.c 
  Log:
  Increase the maximum message queue length to 256, and increase the
  number of cached message structs to the same number.  Modern NICs
  (especially gigabit NICs) often have 64-256 or more receive packet
  descriptors, so they can dump a lot of packets into the network
  stack at once.  With the old message queue limit, it was easy to
  overflow the queue when using the ng_ether node.
  
  I am committing this directly to RELENG_4.  The queuing mechanism is
  quite different in -current, and these limits don't apply there.
