NAME

rte_eth_pfc_queue_conf

SYNOPSIS

#include <rte_ethdev.h>

Data Fields


enum rte_eth_fc_mode mode
uint16_t tx_qid
uint8_t tc
uint16_t pause_time
uint16_t rx_qid

Detailed Description

Warning

EXPERIMENTAL: this API may change, or be removed, without prior notice

A structure used to configure Ethernet priority flow control parameters for ethdev queues.

rte_eth_pfc_queue_conf::rx_pause structure shall be used to configure given tx_qid with corresponding tc. When ethdev device receives PFC frame with rte_eth_pfc_queue_conf::rx_pause::tc, traffic will be paused on rte_eth_pfc_queue_conf::rx_pause::tx_qid for that tc.

rte_eth_pfc_queue_conf::tx_pause structure shall be used to configure given rx_qid. When rx_qid is congested, PFC frames are generated with rte_eth_pfc_queue_conf::rx_pause::tc and rte_eth_pfc_queue_conf::rx_pause::pause_time to the peer.
