Field Documentation

◆ buf_addr

void* buf_addr

Virtual address of segment buffer.

Definition at line 476 of file rte_mbuf_core.h.

◆ next

struct rte_mbuf* next

Next segment of scattered packet. This field is valid when physical address field is undefined. Otherwise next pointer in the second cache line will be used.

Examples: examples/fips_validation/main.c, examples/ipv4_multicast/main.c, examples/vhost/main.c, and examples/vhost/virtio_net.c.

Definition at line 493 of file rte_mbuf_core.h.

◆ ol_flags

uint64_t ol_flags

Offload features.

Examples: examples/bpf/t2.c, examples/ip_fragmentation/main.c, examples/ip_reassembly/main.c, examples/ipsec-secgw/esp.c, examples/ipsec-secgw/ipsec_worker.c, examples/ptpclient/ptpclient.c, and examples/vhost/main.c.

Definition at line 529 of file rte_mbuf_core.h.

◆ pool

struct rte_mempool* pool

Pool from which mbuf was allocated.

Definition at line 615 of file rte_mbuf_core.h.

◆ dynfield2

uint64_t dynfield2

Reserved for dynamic fields when the next pointer is in first cache line (i.e. RTE_IOVA_IN_MBUF is 0).

Definition at line 635 of file rte_mbuf_core.h.

◆ shinfo

struct rte_mbuf_ext_shared_info* shinfo

Shared data for external buffer attached to mbuf. See rte_pktmbuf_attach_extbuf().

Definition at line 678 of file rte_mbuf_core.h.

◆ priv_size

uint16_t priv_size

Size of the application private data. In case of an indirect mbuf, it stores the direct mbuf private data size.

Definition at line 683 of file rte_mbuf_core.h.

◆ timesync

uint16_t timesync

Timesync flags for use with IEEE1588.

Examples: examples/ptpclient/ptpclient.c.

Definition at line 686 of file rte_mbuf_core.h.

◆ dynfield1

uint32_t dynfield1[9]

Reserved for dynamic fields.

Definition at line 688 of file rte_mbuf_core.h.
