(VFIO_PCI_OFFSET_SHIFT) defined in Linux kernel source [1]. It

This patchset implements rte_power_monitor API in virtio and vhost PMD
to reduce power consumption when no packet come in. This API can be
called and tested in l3fwd-power after adding vhost and virtio support
in l3fwd-power and ignoring the rx queue information check in
queue_stopped().
