>New type of VSI has to be defined for switchdev control plane VSI. Number of
>allocated Tx and Rx queue has to be equeal to amount of VFs, because each
>port representor should have one Tx and Rx queue.
>
>Also to not increase number of used irqs too much, control plane VSI uses
>only one q_vector and handle all queues in one irq.
>To allow handling all queues in one irq , new function to clean msix for
>eswitch was introduced. This function will shedule napi for each representor
>instead of sheduling it only for one like in normal clean irq function.
>
>Only one additional msix has to be requested. Always try to request it in
>ice_ena_msix_range function.
