[ovs-dev] Query regarding connection tracking info sent to controller as part of PACKET_IN

[Keshav Gupta]

Hi
       For below pipeline I see different behavior in case of bridge is of type netdev or system. I see in OVS2.6.2 (and OVS 2.8.2) when 
netdev bridge is used conntrack field are sent to controller while in case of kernel bridge it is not sent. So I want to know what is the correct behavior.  In which condition Conn track info in match filed of PACKET_IN message are sent to controller?
