rte_eth_pfc_queue_conf(3) DPDK rte_eth_pfc_queue_conf(3) 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.
