Rework the series\nto base LPM integration on RCU reclaimation APIs.\n\nNew API rte_lpm_rcu_qsbr_add is introduced for application to\nregister a RCU variable that LPM library will use. This provides\nuser the handle to enable RCU that integrated in LPM library.\n\nFunctional tests and performance tests are added to cover the\nintegration with RCU.\n\n---\nv8:\nFixed ABI issue by adding internal LPM control structure. (David)\nChanged to use RFC5737 address in unit test. (Vladimir)\n\nv7:\nFixed typos in document.\n\nv6:\nRemove ALLOW_EXPERIMENTAL_API from rte_lpm.c.\n\nv5:\nNo default value for reclaim_thd. This allows reclamation triggering with every call.\nPass LPM pointer instead of tbl8 as argument of reclaim callback free function.\nUpdated group_idx check at tbl8 allocation.\nUse enums instead of defines for different reclamation modes.\nRCU QSBR integrated path is inside ALLOW_EXPERIMENTAL_API to avoid ABI change.\n\nv4:\nAllow user to configure defer queue: size, reclaim threshold, max entries.\nReturn defer queue handler so user can manually trigger reclaimation.\nAdd blocking mode support. Defer queue will not be created.\n\n\nHonnappa Nagarahalli (1):\n test/lpm: add RCU integration performance tests\n\nRuifeng Wang (2):\n lib/lpm: integrate RCU QSBR\n test/lpm: add LPM RCU integration functional tests\n\n app/test/test_lpm.c | 291 ++++++++++++++++-\n app/test/test_lpm_perf.c | 492 ++++++++++++++++++++++++++++-\n doc/guides/prog_guide/lpm_lib.rst | 32 ++\n lib/librte_lpm/Makefile | 2 +-\n lib/librte_lpm/meson.build | 1 +\n lib/librte_lpm/rte_lpm.c | 167 ++++++++--\n lib/librte_lpm/rte_lpm.h | 53 ++++\n lib/librte_lpm/rte_lpm_version.map | 6 +\n 8 files changed, 1016 insertions(+), 28 deletions(-)" }
