20 -h Show help
21
22 -m max-queue-len
23 Maximum allowed latency, in nanoseconds. If latency to process
24 any packet exceeds this value, the program quits, writing
25 a message to the trace buffer.
26
27 -c cycles-per-packet
28 Estimated number of cycles it takes to process one packet.
29 This value should come from the envisioned packet
30 forwarding application being simulated.
31
32 -p mpps
33 Million packets per second that arrive for processing.
34
35 -f tsc-freq-mhz
36 TSC frequency in MHz.
37
38 -t timeout
39 Timeout in seconds to quit the program.
40
41 -q min_queue_len_to_print_trace
42 Minimum queue length to print in the trace
