uint16_t | pause_time |
uint16_t | rx_qid |
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.
