This structure could be used for both setting and query. All fields should be in host byte order. Definition at line 4027 of file rte_flow.h. Field Documentation uint16_t peer_port The peer port number, can be the same port. Definition at line 4029 of file rte_flow.h. uint32_t is_original_dir Direction of this connection when creating a flow rule, the value only affects the creation of subsequent flow rules. Definition at line 4034 of file rte_flow.h. uint32_t enable Enable / disable the conntrack HW module. When disabled, the result will always be RTE_FLOW_CONNTRACK_FLAG_DISABLED. In this state the HW will act as passthrough. It only affects this conntrack object in the HW without any effect to the other objects. Definition at line 4042 of file rte_flow.h. uint32_t live_connection At least one ack was seen after the connection was established. Definition at line 4044 of file rte_flow.h. uint32_t selective_ack Enable selective ACK on this connection. Definition at line 4046 of file rte_flow.h. uint32_t challenge_ack_passed A challenge ack has passed. Definition at line 4048 of file rte_flow.h. uint32_t last_direction 1: The last packet is seen from the original direction. 0: The last packet is seen from the reply direction. Definition at line 4053 of file rte_flow.h. uint32_t liberal_mode No TCP check will be done except the state change. Definition at line 4055 of file rte_flow.h. enum rte_flow_conntrack_state state The current state of this connection. Definition at line 4057 of file rte_flow.h. uint8_t max_ack_window Scaling factor for maximal allowed ACK window. Definition at line 4059 of file rte_flow.h. uint8_t retransmission_limit Maximal allowed number of retransmission times. Definition at line 4061 of file rte_flow.h. struct rte_flow_tcp_dir_param original_dir TCP parameters of the original direction. Definition at line 4063 of file rte_flow.h. struct rte_flow_tcp_dir_param reply_dir TCP parameters of the reply direction. Definition at line 4065 of file rte_flow.h. uint16_t last_window The window value of the last packet passed this conntrack. Definition at line 4067 of file rte_flow.h. uint32_t last_seq The sequence of the last packet passed this conntrack. Definition at line 4070 of file rte_flow.h. uint32_t last_ack The acknowledgment of the last packet passed this conntrack. Definition at line 4072 of file rte_flow.h. uint32_t last_end The total value ACK + payload length of the last packet passed this conntrack. Definition at line 4077 of file rte_flow.h.
