[ovs-discuss] Issue: ovs send all packets of a table miss entry to controller

[yiyefuping198425]

Hi everyone,
I'm asking for assistance to let ovs only send the first packet of a table miss entry instead of all packets. 
The controller's logs show that ovs would send all packets:

Note: the logs is generated by a packet-in event handler when a flow table entry hard timeouts, with OpenFlow 1.3.
