Field Documentation

◆ rx_thresh

struct rte_eth_thresh rx_thresh

RX ring threshold registers.

Examples:: examples/qos_sched/init.c.

Definition at line 1045 of file rte_ethdev.h.

◆ rx_free_thresh

uint16_t rx_free_thresh

Drives the freeing of RX descriptors.

Examples:: examples/qos_sched/init.c.

Definition at line 1046 of file rte_ethdev.h.

◆ rx_drop_en

uint8_t rx_drop_en

Drop packets if no descriptors are available.

Examples:: examples/multi_process/symmetric_mp/main.c, examples/qos_sched/init.c, examples/vhost/main.c, and examples/vmdq/main.c.

Definition at line 1047 of file rte_ethdev.h.

◆ rx_deferred_start

uint8_t rx_deferred_start

Do not start queue with rte_eth_dev_start().

Examples:: examples/qos_sched/init.c.

Definition at line 1048 of file rte_ethdev.h.

◆ rx_nseg

uint16_t rx_nseg

Number of descriptions in rx_seg array.

Definition at line 1049 of file rte_ethdev.h.

◆ offloads

uint64_t offloads

Per-queue Rx offloads to be set using DEV_RX_OFFLOAD_* flags. Only offloads set on rx_queue_offload_capa or rx_offload_capa fields on rte_eth_dev_info structure are allowed to be set.

Examples:: examples/bond/main.c, examples/eventdev_pipeline/pipeline_worker_generic.c, examples/eventdev_pipeline/pipeline_worker_tx.c, examples/flow_filtering/main.c, examples/ioat/ioatfwd.c, examples/ipsec-secgw/ipsec-secgw.c, examples/kni/main.c, examples/l2fwd-crypto/main.c, examples/l2fwd-event/l2fwd_common.c, examples/l3fwd-acl/main.c, examples/l3fwd/l3fwd_event.c, examples/l3fwd/main.c, examples/multi_process/symmetric_mp/main.c, examples/ntb/ntb_fwd.c, examples/performance-thread/l3fwd-thread/main.c, examples/qos_meter/main.c, examples/qos_sched/init.c, and examples/vhost/main.c.

Definition at line 1055 of file rte_ethdev.h.

◆ rx_seg

union rte_eth_rxseg* rx_seg

Points to the array of segment descriptions for an entire packet. Array elements are properties for consecutive Rx segments.

The supported capabilities of receiving segmentation is reported in rte_eth_dev_info.rx_seg_capa field.

Definition at line 1063 of file rte_ethdev.h.

◆ reserved_64s

uint64_t reserved_64s[2]

Reserved for future fields

Definition at line 1065 of file rte_ethdev.h.

◆ reserved_ptrs

void* reserved_ptrs[2]
