This series introduces a new net virtual device called iavf_client which
is based on vfio-user client interface. Through vfio-user client interface,
PCI liked device could be used similar as Intel® Ethernet Adaptive Virtual
Function specification.
The code to enable iavf_client mainly contains two parts:
 - Emulated pci interfaces for vfio-user client which is located
   in common/iavf/vfio_user/.
 - A new net driver base on vdev abstraction, i.e. iavf_client_ethdev.c

This driver can be used to test the device emulation framework
