Quite honesty, any sort of positive result.  I'm basically just trying to

intended to benefit.

Does semi-polling mode result in less CPU being occupied by "interrupt" 
state at high bandwidth levels when many IPF rules are being used, for 
example?  Do either of these settings result in lower latency or higher 
throughput at high bandwidth levels?

I don't have a firm handle on what specific real-life issues these two new
features were intended to address so I'm not 100% sure how to phrase my
