Originally\nfips_validation tests treats them both as GCM test vectors.\nThis patch introduce automatic test type recognition between\nthe two: when plaintext length is 0 the prepare_gmac_xform\nand prepare_auth_op functions are called, otherwise\nprepare_gcm_xform and prepare_aead_op functions are called.\n\n- NIST GCMVS also specified externally or internally IV\ngeneration. When IV is to be generated by IUT internally IUT\nshall store the generated IV in the response file. This patch\nalso adds the support to that.\n\nSigned-off-by: Fan Zhang <roy.fan.zhang@intel.com>\nSigned-off-by: Weqaar Janjua <Weqaar.A.Janjua@intel.com>\n---\n doc/guides/rel_notes/release_20_11.rst
