Field Documentation

uint16_tpeer_port
The peer port number, can be the same port.

Definition at line 4029 of file rte_flow.h.

uint32_tis_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_tenable
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_tlive_connection
At least one ack was seen after the connection was established.

Definition at line 4044 of file rte_flow.h.

uint32_tselective_ack
Enable selective ACK on this connection.

Definition at line 4046 of file rte_flow.h.

uint32_tchallenge_ack_passed
A challenge ack has passed.

Definition at line 4048 of file rte_flow.h.

uint32_tlast_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_tliberal_mode
No TCP check will be done except the state change.

Definition at line 4055 of file rte_flow.h.

enumrte_flow_conntrack_statestate
The current state of this connection.

Definition at line 4057 of file rte_flow.h.

uint8_tmax_ack_window
Scaling factor for maximal allowed ACK window.

Definition at line 4059 of file rte_flow.h.

uint8_tretransmission_limit
Maximal allowed number of retransmission times.

Definition at line 4061 of file rte_flow.h.

structrte_flow_tcp_dir_paramoriginal_dir
TCP parameters of the original direction.

Definition at line 4063 of file rte_flow.h.

structrte_flow_tcp_dir_paramreply_dir
TCP parameters of the reply direction.

Definition at line 4065 of file rte_flow.h.

uint16_tlast_window
The window value of the last packet passed this conntrack.

Definition at line 4067 of file rte_flow.h.

uint32_tlast_seq
The sequence of the last packet passed this conntrack.

Definition at line 4070 of file rte_flow.h.

uint32_tlast_ack
The acknowledgment of the last packet passed this conntrack.

Definition at line 4072 of file rte_flow.h.

uint32_tlast_end
The total value ACK + payload length of the last packet passed this conntrack.

Definition at line 4077 of file rte_flow.h.
