Introduce 2 new flow table types:\n\n1. Allow a user to specify the insertion type used in template tables.\nThe insertion type is responsible for choosing the appropriate key\nvalue used to map inserted flow rules into a template table.\n\nFlow rules can be inserted by calculating the hash value for\nthe pattern or inserted by index via the new create_by_index() API.\nThe idea of the index-based insertion is to avoid additional matches\nand simply execute predefined actions after jumping to the index.\n\nThe insertion into an already occupied index results in an error.\nThe old rule must be destroyed first. An index cannot be bigger than\nthe size of the table, otherwise, the rule is rejected as well.\n\n2. Allow a user to specify the hash calculation function used in template\ntables. The hash calculation type is responsible for the calculation of\nthe flow rule index a packet would hit upon arrival at the table.\n\nControl over this is useful for applications with custom RSS algorithms,\nfor example. An application can select various packet fields to serve as\na hash calculation source and jump to the appropriate flow rule location.\nThe RSS hash result will be used as the index in the table. For the linear\nhash function, the mapping is one-to-one and the hash result is the index.\nFor other hash functions, the index is the hash result module table size.\nThe RSS hash result can be retrieved via modify_field API: HASH_RESULT.\n\nRFC: https://patchwork.dpdk.org/project/dpdk/patch/20221214022110.393410-1-akozyrev@nvidia.com/\nv2: changed the behavior in case of insertion into the same index.\n \nAlexander Kozyrev (4):\n ethdev: add template table insertion type\n ethdev: add template table hash calculation function\n app/testpmd: add template table insertion type\n app/testpmd: add template table hash calculation function\n\n app/test-pmd/cmdline_flow.c | 166 +++++++++++++++++++++++--\n app/test-pmd/config.c | 10 +-\n app/test-pmd/testpmd.h | 2 +-\n doc/guides/prog_guide/rte_flow.rst | 20 +++\n doc/guides/rel_notes/release_23_03.rst | 10 ++\n lib/ethdev/rte_flow.c | 24 ++++\n lib/ethdev/rte_flow.h | 95 ++++++++++++++\n lib/ethdev/rte_flow_driver.h | 11 ++\n lib/ethdev/version.map | 3 +\n 9 files changed, 330 insertions(+), 11 deletions(-)" }
