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

Parameters

op The crypto operation to be reset.

Definition at line 887 of file rte_crypto_sym.h.

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

Attach a session to a symmetric crypto operation

Parameters

sym_op crypto operation
sess cryptodev session

Definition at line 927 of file rte_crypto_sym.h.

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

  • number of successfully filled entries in vec array.
  • negative number of elements in vec array required.
