Hi, I am trying to port OVS to a hardware switch. I read the INSTALL* and PORTING documents and I going through the code to understand the current implementation. I understand that I would have to implement a ofproto provider and a netdev provider. I compiled OVS without the kernel support and I ran it on the switch and I am able to connect to the controller.
The ofproto-dpif implementation supports two datapath types "netdev" and "system". Why are they used? The netdev provider initializes three types of devices "system", "internal" and "tap". Why are they used? Is one of them used for the openflow controller connection? Thanks, Harsha
