This patch is used to detect the nvme and ioat devices in the tested platform and bind it to uio_pci_generic driver. Thus, when we can smoothly use pci device functions provided by DPDK instead of using libpciaccess. Change-Id: Ibfe504fd2864c9b4980eacd0adc5ff2a029b5eaf Signed-off-by: Ziye Yang <ziye.yang@intel.com>
