3. I did some debug on ovs-switchd, and it seemed that when do dpdk_init(),
the function rte_eal_pci_map_device() return -1, so the whole vswtiched
process exited.
some deep debug shows that VFIO_PRESENT is not defined, but now my kernel
version is:
Linux 10-180-0-39 3.10.45-openstack-amd64, which is greater than 3.6.0
