Detailed Description

RTE PDCP grouping support. It is not recommended to include this file directly, include <rte_pdcp.h> instead. Provides helper functions to process completed crypto-ops and group related packets by sessions they belong to.

Function Documentation

◆ rte_pdcp_en_from_cop()

static struct rte_pdcp_entity* rte_pdcp_en_from_cop ( const struct rte_crypto_op cop)
static
Warning
EXPERIMENTAL: this API may change without prior notice.

Take crypto-op as an input and extract pointer to related PDCP entity.

Parameters
copThe address of an input rte_crypto_op structure.
Returns
The pointer to the related rte_pdcp_entity structure.

Definition at line 50 of file rte_pdcp_group.h.

◆ rte_pdcp_pkt_crypto_group()

static uint16_t rte_pdcp_pkt_crypto_group ( struct rte_crypto_op cop[],
struct rte_mbuf mb[],
struct rte_pdcp_group  grp[],
uint16_t  num 
)
inlinestatic
Warning
EXPERIMENTAL: this API may change without prior notice.

Take as input completed crypto ops, extract related mbufs and group them by rte_pdcp_entity they belong to. Mbuf for which the crypto operation has failed would be flagged using RTE_MBUF_F_RX_SEC_OFFLOAD_FAILED flag in rte_mbuf.ol_flags. The crypto_ops would be freed after the grouping.

Note that application must ensure only crypto-ops prepared by lib_pdcp is provided back to

See also
rte_pdcp_pkt_crypto_group().
Parameters
copThe address of an array of num pointers to the input rte_crypto_op structures.
[out]mbThe address of an array of num pointers to output rte_mbuf structures.
[out]grpThe address of an array of num to output rte_pdcp_group structures.
numThe maximum number of crypto-ops to process.
Returns
Number of filled elements in grp array.
