My apologies, I have missed it. The reason for this change was to keep a little bit better order in this fi= le. So previously we have had: -defines -enums -algorithms xfroms -algorithms ops -asym xform -asym op now we got: -defines -enums -algorithms xfroms -algorithms ops -asym xform -------------SM2 OP -asym op I know it is not a game changer, but helps to keep a better order in this f= ile. If this is problematic then I can revert it.=20 >=20 >=20 > > -/** > > * SM2 operation params. > > */ > > struct rte_crypto_sm2_op_param { > > @@ -658,20 +624,43 @@ struct rte_crypto_sm2_op_param { > > * will be overwritten by the PMD with the decrypted length. > > */ > > > > - rte_crypto_param cipher; > > - /**< > > - * Pointer to input data > > - * - to be decrypted for SM2 private decrypt. > > - * > > - * Pointer to output data > > - * - for SM2 public encrypt. > > - * In this case the underlying array should have been allocated > > - * with enough memory to hold ciphertext output (at least X bytes > > - * for prime field curve of N bytes and for message M bytes, > > - * where X =3D (C1 || C2 || C3) and computed based on SM2 RFC as > > - * C1 (1 + N + N), C2 =3D M, C3 =3D N.
