    "content": "- Moved dh operation type to dh operation struct.\nOperation type (PUBLIC_KEY_GENERATION, SHARED_SECRET) should\nbe free to choose for any operation. One xform/session should\nbe enough to perform both DH operations, if op_type would be xform\nmember, session would have to be to be created twice for the same\ngroup. Similar problem would be observed in sessionless case.\nAdditionally, it will help extend DH to support Elliptic Curves.\n- Changed order of Diffie-Hellman operation phases.\nNow it corresponds with the order of operations.\n\nSigned-off-by: Arek Kusztal <arkadiuszx.kusztal@intel.com>\n---\n app/test/test_cryptodev_asym.c               | 11 +++++------\n drivers/crypto/openssl/rte_openssl_pmd.c     | 15 ++++++---------\n drivers/crypto/openssl/rte_openssl_pmd_ops.c | 27 ---------------------------\n lib/cryptodev/rte_crypto_asym.h              | 22 ++++++++++------------\n 4 files changed, 21 insertions(+), 54 deletions(-)",
