I use a mini pc with i.mx6 dual and Intel igb based nic (I211) connected via PCIE. igb driver uses MSI-X and creates two rx/tx queue pairs. However the IRQs of all queues are handled by the same CPU. Changing affinity is not possible. Obvious direct reason is that irq_chip PCI-MSI doesn't implement the callback for setting cpu affinity. I'd appreciate a hint whether this is a general limitation of the Cortex-A9 / GICv1 / Synopsys Designware architecture or whether just a proper implementation is missing yet.
