Hi,  
I want to collect bi-directional netflow generated by nprobe and suricata. But it seems with the netflow module the output is always converted to uni-directional flows.  
Is that expected, a bug or have i overlooked an option?

I am wondering because with the logstash netflow input codec i get the expected bi-directional flow output (when collecting bi-directional flows).
