> Current default ITR interval I40E_QUEUE_ITR_INTERVAL_DEFAULT is
> used by both DPDK PF and DPDK VF, but this ITR interval value
> will cause lots of interrupts when using VF. This patch modifies
> VF default ITR interval to reduce interrupts.
> ITR interval can be configured by RTE_LIBRTE_I40E_ITR_INTERVAL
> if expecting low latency.
