SYNOPSIS

       #include <rte_ethdev.h>

   Data Fields
       enum rte_eth_fc_mode mode

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.
