Hello I downloaded the openvswitch-1.11.0 source code and started experimenting with it.I am having the following doubts
1. What is the difference between the flow entries maintained in the Kernel datapath and the Userspace Openflow switch. 2. Does ovs-ofctl add-flow command adds the flow entries both in the Kernel and userspace ? If this is not adding the flows in the kernel datapath , then how to add the flows in the kernel datapath? 3. When I am dumping the flows using ovs-ofctl dump-flows those are the flows in the kernel datapath or in the userspace openflow switch. 4. When the userspace switch receives the flow mod from the controller will the flow be added both in the userspace and kernel space table. If so can you please point me to the relevant function call while handling the flow mod , to add the flow to the kernel datapath. Can you people please help me out. Thanks in Advance. --Rakesh
