[v2,0/6] introduce iavf backend driver

This series introduces a net device driver called iavfbe which is working
as datapath driver for emulated iavf type device. It provides basic function
following Intel® Ethernet Adaptive Virtual Function specification, including
recevice/transmit packets and virtchnl control messages handling.
The driver enabling work is based on the framework mentioned in:
  [RFC 0/2] Add device emulation support in DPDK
  http://patchwork.dpdk.org/cover/75549/
