V6 Changes: * Added new mempool flag to ensure mbuf memory is not scattered across page boundaries. * Added KNI kernel module required PCI device information. * Modified KNI example application to create mempool with new mempool flag. V5 changes: * Fixed build issue with 32b build V4 changes: * Fixed build issues with older kernel versions * This approach will only work with kernel above 4.4.0 V3 Changes: * Add new approach to work kni with IOVA=VA mode using iommu_iova_to_phys API.
