V14 Changes:
* Simplified forcing IOVA as PA scheme.
* Updated documentation
V13 Changes:
* For KNI case, to restore the existing behaviour, forcing IOVA as PA
if bus iommu returns IOVA_DC.
* Restored phys_addr and kni_lib defination checks.
* Simplified patch titles.
* Updated documentation about patch set's impact on performance and
kernel version requirement.
V12 Changes:
* Removed previously added `--legacy-kni` eal option.
* Removed previously added kni specific mempool create routines
and mempool populate routines.
V11 Changes:
* Added iova to kva address translation routines in kernel module to
make it work in iova=va mode which enables DPDK to create kni devices
on any kind of backed device/memory.
* Added ``--legacy-kni`` eal option to make existing KNI applications
work with DPDK 19.11 and later versions.
* Removed previously added pci device info from kni device info struct.
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
