Thjanks for the tip.  As it turns out it's creating one queue per cpu, 
we just had all the interrupts on cpu0.  I had assumed otherwise based 
on how the question was posed to me, but I should have gone and checked 
personally on the real hardware.

Looking at the driver (version 3.6.7) I'm a bit confused as to how it 
manages to get 32 queues when the hardware only supports 16 RSS queues. 
  Does the line in ixgbe_param.c about "limit the number of queues for 
FDIR using RSS param" only apply if we explicitly set the number of RSS 
queues?
