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?
