Just consider about the interactive mode.
If using command start, will it still call start_packet_forwarding(0)?
And if start tx_first, still call start_packet_forwarding(1)?

It may cause confused whether this argu "--tx-first" works.
If it only works for non-interactive, you'd better to comment it.


Thanks
