## Field Documentation

### uint16\_t flags

Flags from RTE\_NTUPLE\_FLAGS\_\*

Definition at line **51** of file **rte\_eth\_ctrl.h**.

### uint32\_t dst\_ip

Destination IP address in big endian.

Definition at line **52** of file **rte\_eth\_ctrl.h**.

### uint32\_t dst\_ip\_mask

Mask of destination IP address.

Definition at line **53** of file **rte\_eth\_ctrl.h**.

### uint32\_t src\_ip

Source IP address in big endian.

Definition at line **54** of file **rte\_eth\_ctrl.h**.

### uint32\_t src\_ip\_mask

Mask of destination IP address.

Definition at line **55** of file **rte\_eth\_ctrl.h**.

### uint16\_t dst\_port

Destination port in big endian.

Definition at line **56** of file **rte\_eth\_ctrl.h**.

### uint16\_t dst\_port\_mask

Mask of destination port.

Definition at line **57** of file **rte\_eth\_ctrl.h**.

### uint16\_t src\_port

Source Port in big endian.

Definition at line **58** of file **rte\_eth\_ctrl.h**.

### uint16\_t src\_port\_mask

Mask of source port.

Definition at line **59** of file **rte\_eth\_ctrl.h**.

### uint8\_t proto

L4 protocol.

Definition at line **60** of file **rte\_eth\_ctrl.h**.

### uint8\_t proto\_mask

Mask of L4 protocol.

Definition at line **61** of file **rte\_eth\_ctrl.h**.

### uint8\_t tcp\_flags

tcp\_flags only meaningful when the proto is TCP. The packet matched above ntuple fields and contain any set bit in tcp\_flags will hit this filter.

Definition at line **65** of file **rte\_eth\_ctrl.h**.

### uint16\_t priority

seven levels (001b-111b), 111b is highest, used when more than one filter matches.

Definition at line **66** of file **rte\_eth\_ctrl.h**.

### uint16\_t queue

Queue assigned to when match

Definition at line **68** of file **rte\_eth\_ctrl.h**.
