This patch implements vDPA driver ops which configures ifc VF to be a vhost data path accelerator. ifcvf driver uses vdev as a control domain to manage ifc VFs that belong to it. It registers vDPA device ops to vhost lib to enable these VFs to be used as vhost data path accelerator. Live migration feature is supported by ifc VF and this driver enables it based on vhost lib. vDPA needs to create different containers for different devices, thus this patch set adds some APIs in eal/vfio to support multiple container, e.g. - rte_vfio_create_container - rte_vfio_destroy_container - rte_vfio_bind_group_no - rte_vfio_unbind_group_no By this extension, a device can be put into a new specific container, rather than the previous default container. v2: - Rename function pci_get_kernel_driver_by_path to rte_pci_device_kdriver_name to make the API generic cross Linux and BSD, make it as EXPERIMENTAL. - Rebase on Zhihong's vDPA v3 patch set. - Minor code cleanup on vfio extension.
