   Lastly from the software side Linux doesn't seem to have anything like
   BSD's parameter to control user/system CPU sharing.  Once my CPU load
   reaches 70-80%, I'd rather have some dropped packets than let the CPU hit
   100% and end up with my BGP sessions drop.

When packet (more specifically, software interrupt) processing
reaches a certain level, we offload the work into process context.

That sounds good.  Is there a sysctl I can use to define "certain level"?
