Aren't OVS ports trunks by default? I tried matching dl_type=0x8100 as well as dl_vlan without explicitly setting ports as trunks. But it also did not work.
So what options do I have, if I have to pass tagged traffic through OVS? or if i have to take certain actions against tagged traffic?

There are two issues here. First, VLAN 0 includes untagged traffic.
Second, "trunks" affects only the behavior of the "normal" action. It
does not influence other OpenFlow matches or actions in any way.
