Definition at line 131 of file rte_security.h.

◆ copy_dscp

uint32_t copy_dscp

Copy DSCP bits

1: Copy IPv4 or IPv6 DSCP bits from inner IP header to the outer IP header in encapsulation, and vice versa in decapsulation.
0: Do not change DSCP field.

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

Definition at line 140 of file rte_security.h.

◆ copy_flabel

uint32_t copy_flabel

1: Copy the DF bit from the inner IPv4 header to the outer IPv4 header.
0: Outer header is not modified.

Definition at line 156 of file rte_security.h.

◆ dec_ttl

uint32_t dec_ttl

Decrement inner packet Time To Live (TTL) field

1: In tunnel mode, decrement inner packet IPv4 TTL or IPv6 Hop Limit after tunnel decapsulation, or before tunnel encapsulation.
0: Inner packet is not modified.

Definition at line 165 of file rte_security.h.

◆ ecn

uint32_t ecn

Explicit Congestion Notification (ECN)

1: In tunnel mode, enable outer header ECN Field copied from inner header in tunnel encapsulation, or inner header ECN field construction in decapsulation.
