According to our\nmeasurements on SKX for 1M entries average lookup cost is ~80 cycles,\naverage add cost ~500 cycles.\n\nNext Steps:\n- integration with ipsec-secgw\n- documentation\n\nv3:\n- fixes in rte_ipsec_sad_create() and rte_ipsec_sad_find_existing()\n- fix typos\n- updated commit messages\n\nv2:\n- various bugs fixed\n- rte_ipsec_sad_free renamed to rte_ipsec_sad_destroy\n- added const qualifier to rte_ipsec_sad_key *key for add/delete\n- added more comments into the code\n- added ipv6 support into the testsad app\n- added <DEL> measurement into the testsad app\n- random SPI values are generated without dups\n- added support for configurable burst size in testsad app\n- added verbose mode into the testsad app\n\nVladimir Medvedkin (5):\n ipsec: add inbound SAD API\n ipsec: add SAD create/destroy implementation\n ipsec: add SAD add/delete/lookup implementation\n test/ipsec: add ipsec SAD autotests\n app: add test-sad application\n\n app/Makefile | 1 +\n app/meson.build | 3 +-\n app/test-sad/Makefile | 18 +\n app/test-sad/main.c | 662 ++++++++++++++++++++++++\n app/test-sad/meson.build | 6 +\n app/test/Makefile | 1 +\n app/test/autotest_data.py | 6 +\n app/test/meson.build | 1 +\n app/test/test_ipsec_sad.c | 885 +++++++++++++++++++++++++++++++++\n lib/librte_ipsec/Makefile | 4 +-\n lib/librte_ipsec/ipsec_sad.c | 520 +++++++++++++++++++\n lib/librte_ipsec/meson.build | 6 +-\n lib/librte_ipsec/rte_ipsec.h | 1 +\n lib/librte_ipsec/rte_ipsec_sad.h | 175 +++++++\n lib/librte_ipsec/rte_ipsec_version.map | 7 +\n 15 files changed, 2291 insertions(+), 5 deletions(-)\n create mode 100644 app/test-sad/Makefile\n create mode 100644 app/test-sad/main.c\n create mode 100644 app/test-sad/meson.build\n create mode 100644 app/test/test_ipsec_sad.c\n create mode 100644 lib/librte_ipsec/ipsec_sad.c\n create mode 100644 lib/librte_ipsec/rte_ipsec_sad.h" }
