Function Documentation

static void __rte_crypto_sym_op_reset ( struct rte_crypto_sym_op *  op )

inlinestatic

Reset the fields of a symmetric operation to their default values.

Parameters

op	The crypto operation to be reset.

Definition at line 636 of file rte_crypto_sym.h.

static struct rte_crypto_sym_xform* __rte_crypto_sym_op_sym_xforms_alloc ( struct rte_crypto_sym_op *  sym_op, void *  priv_data, uint8_t  nb_xforms  )
