Subject: raw/ifpga: support lightweight FPGA image
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e21346c4392b9d9a0f7429ab2b0b632f6bdc69e4;p=dpdk.git

raw/ifpga: support lightweight FPGA image

if fpga image support lightweight feature, set afu uuid to all 0, ipn3ke
representor will not be probed.
