added kni specific mempool create routines\nand mempool populate routines.\n\nThis patch set(V12) is dependent on following patch set, since the mempool\nrelated support to enable KNI in IOVA=VA mode is taken care in below\npatchset.\n\n https://patchwork.dpdk.org/cover/62376/\n\nV11 Changes:\n* Added iova to kva address translation routines in kernel module to\nmake it work in iova=va mode which enables DPDK to create kni devices\non any kind of backed device/memory.\n* Added ``--legacy-kni`` eal option to make existing KNI applications\nwork with DPDK 19.11 and later versions.\n* Removed previously added pci device info from kni device info struct.\n \nV10 Changes:\n* Fixed function return code on failure when min_chunk_size > pg_sz.\n* Marked new mempool populate routine as EXPERIMENTAL.\n \nV9 Changes:\n* Used rte_mempool_ops_calc_mem_size() instead of default handler in the\nnew mempool populate routine.\n* Check min_chunk_size and return values.\n* Removed ethdev_info memset to '0' and moved pci dev_info populate into\nkni_dev_pci_addr_get() routine.\n* Addressed misc. review comments.\n \nV8 Changes:\n* Remove default mempool populate() routine changes.\n* Add kni app specific mempool create & free routines.\n* Add new mempool populate routine to allocate page-aligned memzones\nwith page size to make sure all mempool objects reside on a page.\n* Update release notes and map files.\n \nV7 Changes:\n* Removed previously proposed mempool flag and made those page\nboundary checks default in mempool populate() except for the objects size\nbigger than the size of page.\n* Removed KNI example application related changes since pool related\nrequirement is taken care in mempool lib.\n* All PCI dev related info is moved under rte_eal_iova_mode() == VA check.\n* Added wrapper functions in KNI module to hide IOVA checks and make\naddress translation routines more readable.\n* Updated IOVA mode checks that enforcing IOVA=PA mode when IOVA=VA\nmode is enabled.\n \nV6 Changes:\n* Added new mempool flag to ensure mbuf memory is not scattered across\npage boundaries.\n* Added KNI kernel module required PCI device information.\n* Modified KNI example application to create mempool with new mempool\nflag.\n \nV5 changes:\n* Fixed build issue with 32b build\n \nV4 changes:\n* Fixed build issues with older kernel versions\n* This approach will only work with kernel above 4.4.0\n \nV3 Changes:\n* Add new approach to work kni with IOVA=VA mode using\niommu_iova_to_phys API.\n\nVamsi Attunuru (2):\n kni: add IOVA=VA mode support\n kni: add IOVA=VA support in
