    dummynet - Poll only if operational, change default freq for vkernel
    
    * Default frequency for vkernel is now 100 hz instead of 1000 hz.
      The frequency can be changed at any time with a sysctl.
    
    * The systimer is only configured when there are pipes or flows
      present, and will be deconfigured when there aren't.  This
      saves us from doing any unnecessary polling.
    
    * dummynet still has some considerable holes related to SMP
      operation.  It really needs a rewrite to some degree.
