The ESP header's sequence number is\nunique and has to be sequentially incremented in an orderly manner.\nThis rises a need for incrementing sequence number in crypto stage\nespecially in event crypto adapter. By adding a user callback to\ncryptodev at enqueue burst, the user callback will get executed\nin the context of event crypto adapter. This helps the application\nto increment the ESP sequence number atomically and orderly manner.\nThe user callback at the dequeue burst helps IPsec application to\ntake care of ARW processing.\n\nv4->v5:\n -Added dequeue callback APIs\n -Updated documentation\n -Updated errno and return values\n -Updated cleanup function\n\nv3->v4:\n -Move callback init and cleanup under dev_configure\n -Update with memory ordering\n -Removed extra level of indirection\n -Add documentation\n\nv2->v3:\n -Moved RCU under the cryptodev APIs\n -RCU is maintained per queue-pair\n -Changed name of few variables\n -Updated callback test with negative cases\n -Updated with required changes for meson\n\nv1->v2:\n -Moved callback related members to the end of cryptodev struct\n -Added support for RCU\n\nAbhinandan Gujjar (2):\n cryptodev: support enqueue & dequeue callback functions\n test: add testcase for crypto enqueue callback\n\n app/test/test_cryptodev.c | 135 +++++++-\n config/rte_config.h | 1 +\n doc/guides/prog_guide/cryptodev_lib.rst | 47 +++\n doc/guides/rel_notes/release_20_11.rst | 6 +\n lib/librte_cryptodev/meson.build | 2 +-\n lib/librte_cryptodev/rte_cryptodev.c | 419 ++++++++++++++++++++++++-\n lib/librte_cryptodev/rte_cryptodev.h | 260 ++++++++++++++-\n lib/librte_cryptodev/rte_cryptodev_version.map | 4 +\n 8 files changed, 869 insertions(+), 5 deletions(-)" }
