void * priv_data, uint8_t nb_xforms) [inline], [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

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
