Field Documentation

◆ rx_thresh

struct rte_eth_thresh rx_thresh

Rx ring threshold registers.

Examples:
examples/qos_sched/init.c.

Definition at line 1208 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 1209 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 1210 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 1211 of file rte_ethdev.h.

◆ rx_nseg

uint16_t rx_nseg

Number of descriptions in rx_seg array.

Definition at line 1212 of file rte_ethdev.h.

◆ share_group

uint16_t share_group

Share group index in Rx domain and switch domain. Non-zero value to enable Rx queue share, zero value disable share. PMD is responsible for Rx queue consistency checks to avoid member port's configuration contradict to each other.

Definition at line 1219 of file rte_ethdev.h.

◆ share_qid

uint16_t share_qid

Shared Rx queue ID in group

Definition at line 1220 of file rte_ethdev.h.

◆ offloads

uint64_t offloads

◆ 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 1234 of file rte_ethdev.h.

◆ reserved_64s

uint64_t reserved_64s[2]

Reserved for future fields

Definition at line 1236 of file rte_ethdev.h.

◆ reserved_ptrs

void* reserved_ptrs[2]

Reserved for future fields

Definition at line 1237 of file rte_ethdev.h.
