Field Documentation

struct rte_eth_thresh rx_thresh

RX ring threshold registers.

Definition at line 1039 of file rte_ethdev.h.

uint16_t rx_free_thresh

Drives the freeing of RX descriptors.

Definition at line 1040 of file rte_ethdev.h.

uint8_t rx_drop_en

Drop packets if no descriptors are available.

examples/vhost/main.c, and examples/vmdq/main.c.

Definition at line 1041 of file rte_ethdev.h.

uint8_t rx_deferred_start

Do not start queue with rte_eth_dev_start().

Definition at line 1042 of file rte_ethdev.h.

uint16_t rx_nseg

Number of descriptions in rx_seg array.

Definition at line 1043 of file rte_ethdev.h.

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/l2fwd-event/l2fwd_common.c, and examples/vhost/main.c.

Definition at line 1049 of file rte_ethdev.h.

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.
