[dpdk-dev] [RFC 0/4] Intel FPGA Bus

[Rosen Xu]

With Partial Reconfigure(PR) parts of Bitstream, Field Programmable Gate Array(FPGA) not only 
provides one kinds of accelerator but also provides many types of accelerators at the same time.

How DPDK fully support FPGA?
 - We use Rawdev to provide FPGA PR
 - DPDK Driver will not bind to PCI Device it will bind to FPGA Partial-Bitstream(AFU,Accelerated Function Unit)
 - For the new Device scan, driver probe, we involve Intel FPGA Bus Module

This patchset is base on v18.02.
