V7 Changes: * Removed previously proposed mempool flag and made those page boundary checks default in mempool populate() except for the objects size bigger than the size of page. * Removed KNI example application related changes since pool related requirement is taken care in mempool lib. * All PCI dev related info is moved under rte_eal_iova_mode() == VA check. * Added wrapper functions in KNI module to hide IOVA checks and make address translation routines more readable. * Updated IOVA mode checks that enforcing IOVA=PA mode when IOVA=VA mode is enabled. 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.
