## Field Documentation

### struct rte\_mempool\* pool

Buffer pool. Must be valid.

Definition at line **26** of file **rte\_swx\_port\_source\_sink.h**.

### const char\* file\_name

Name of a valid PCAP file to read the input packets from.

Definition at line **29** of file **rte\_swx\_port\_source\_sink.h**.

### uint64\_t n\_loops

Number of times to loop through the input PCAP file. Loop infinite times when set to 0.

Definition at line **34** of file **rte\_swx\_port\_source\_sink.h**.

### uint32\_t n\_pkts\_max

Maximum number of packets to read from the PCAP file. When 0, it is internally set to RTE\_SWX\_PORT\_SOURCE\_PKTS\_MAX. Once read from the PCAP file, the same packets are looped forever.
