V10 Changes:
* Fixed function return code on failure when min_chunk_size > pg_sz.
* Marked new mempool populate routine as EXPERIMENTAL.
V9 Changes:
* Used rte_mempool_ops_calc_mem_size() instead of default handler in
the new mempool populate routine.
* Check min_chunk_size and return values.
* Removed ethdev_info memset to '0' and moved pci dev_info populate into
kni_dev_pci_addr_get() routine.
* Addressed misc. review comments.
V8 Changes:
* Remove default mempool populate() routine changes.
* Add kni app specific mempool create & free routines.
* Add new mempool populate routine to allocate page-aligned memzones
with page size to make sure all mempool objects reside on a page.
* Update release notes and map files.
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.
