I assume you are talking about an ixgbe NIC, probably something like an x540 or an 82599? It would be helpful to specify the driver and which specific NIC we are talking about. > Now, the redirection table lists cores 0...11 and I'm confused. I verified > that counters of interrupts on cores 0..11 are not growing for this card. The redirection table lists queues, not cores. The interrupt affinity is what determines what queue will be routed to what core.
