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
mentioned in:

It can be launched together with patch series for the testing:
[0/9] Introduce vfio-user library:

[0/8]Introduce emudev library and iavf emudev driver
http://patchwork.dpdk.org/cover/85488/
This series depends on patch serieses:
