Detailed Description

RTE Security Common Definitions

Definition in file rte_security.h.

Macro Definition Documentation

#define RTE_SECURITY_PDCP_ORDERING_CAP   0x00000001

Underlying Hardware/driver which support PDCP may or may not support packet ordering. Set RTE_SECURITY_PDCP_ORDERING_CAP if it support. If it is not set, driver/HW assumes packets received are in order and it will be application's responsibility to maintain ordering.

Definition at line 695 of file rte_security.h.

#define RTE_SECURITY_PDCP_DUP_DETECT_CAP   0x00000002

Underlying Hardware/driver which support PDCP may or may not detect duplicate packet. Set RTE_SECURITY_PDCP_DUP_DETECT_CAP if it support. If it is not set, driver/HW assumes there is no duplicate packet received.

Definition at line 701 of file rte_security.h.

#define RTE_SECURITY_TX_OLOAD_NEED_MDATA   0x00000001

HW needs metadata update, see rte_security_set_pkt_metadata().

Examples:
examples/ipsec-secgw/ipsec.c, and examples/ipsec-secgw/ipsec_worker.c.

Definition at line 703 of file rte_security.h.

#define RTE_SECURITY_TX_HW_TRAILER_OFFLOAD   0x00000002

HW constructs trailer of packets Transmitted packets will have the trailer added to them by hardware. The next protocol field will be based on the mbuf->inner_esp_next_proto field.

Examples:
examples/ipsec-secgw/esp.c, and examples/ipsec-secgw/ipsec.c.

Definition at line 707 of file rte_security.h.

#define RTE_SECURITY_RX_HW_TRAILER_OFFLOAD   0x00010000

HW removes trailer of packets Received packets have no trailer, the next protocol field is supplied in the mbuf->inner_esp_next_proto field. Inner packet is not modified.

Examples:
examples/ipsec-secgw/esp.c.
