Field Documentation

struct rte_eth_thresh tx_thresh

TX ring threshold registers.

Definition at line 855 of file rte_ethdev.h.

uint16_t tx_rs_thresh

Drives the setting of RS bit on TXDs.

Definition at line 856 of file rte_ethdev.h.

uint16_t tx_free_thresh

Start freeing TX buffers if there are less free descriptors than this value.

Definition at line 857 of file rte_ethdev.h.

uint8_t tx_deferred_start

Do not start queue with rte_eth_dev_start().

Definition at line 860 of file rte_ethdev.h.

uint64_t offloads

Per-queue Tx offloads to be set using DEV_TX_OFFLOAD_* flags. Only offloads set on tx_queue_offload_capa or tx_offload_capa fields on rte_eth_dev_info structure are allowed to be set.
