It wraps around rte_lpm [1] library.This library implements variation of DIR24-8 [2] lookup algorithm.Module provide lockless route lookups and in-place incremental updates, allowing for good RIB performance.IPv6 module is called dpdk_lpm6. It wraps around rte_lpm6 [3] library.Implementation can be seen as multi-bit trie where the stride or number of bits inspected on each level varies from level to level.It can vary from 1 to 14 memory accesses, with 5 being the average value for the lengths that are most commonly used in IPv6.Module provide lockless route lookups for global unicast addresses and in-place incremental updates, allowing for good RIB performance.Implementation details:* wrapper code lives in `sys/contrib/dpdk_rte_lpm/dpdk_lpm[6].c`.* rte_lpm[6] implementation contains both RIB and FIB code. . RIB ("rule_") code, backed by array of hash tables part has been commented out, as base radix already provides all the necessary primitives.* link-local lookups are currently implemented as base radix lookup. This part should be converted to something like read-only radix trie.Usage detail:Compile kernel with option FIB_ALGO and load dpdk_lpm4/dpdk_lpm6 module at any time. They will be picked up automatically when amount of routes raises to several thousand.[1]: https://doc.dpdk.org/guides/prog_guide/lpm_lib.html[2]: http://yuba.stanford.edu/~nickm/papers/Infocom98_lookup.pdf[3]: https://doc.dpdk.org/guides/prog_guide/lpm6_lib.htmlDifferential Revision: https://reviews.freebsd.org/D27412 List of files: /freebsd/sys/modules/dpdk_lpm4/Makefile Sat, 09 Jan 2021 13:08:00 +0100 Alexander V.
