Function Documentation

__rte_crypto_sym_op_reset()

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 883 of file rte_crypto_sym.h.

__rte_crypto_sym_op_sym_xforms_alloc()

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  )

static

Allocate space for symmetric crypto xforms in the private data space of the crypto operation. This also defaults the crypto xform type to RTE_CRYPTO_SYM_XFORM_NOT_SPECIFIED and configures the chaining of the xforms in the crypto operation

Returns

• On success returns pointer to first crypto xform in crypto operations chain
• On failure returns NULL

Definition at line 900 of file rte_crypto_sym.h.

__rte_crypto_sym_op_attach_sym_session()

static int __rte_crypto_sym_op_attach_sym_session ( struct rte_crypto_sym_op *  sym_op, void *  sess  )

inlinestatic

Attach a session to a symmetric crypto operation

Parameters

sym_op	crypto operation
sess	cryptodev session

Definition at line 923 of file rte_crypto_sym.h.

rte_crypto_mbuf_to_vec()

inlinestatic

Converts portion of mbuf data into a vector representation. Each segment will be represented as a separate entry in vec array. Expects that provided ofs + len not to exceed mbuf's pkt_len.

Parameters

mb	Pointer to the rte_mbuf object.
ofs	Offset within mbuf data to start with.
len	Length of data to represent.
vec	Pointer to an output array of IO vectors.
num	Size of an output array.

Returns
