Hi, (Note: When kernel module is loaded things work fine)
I am testing userspace OVS and having trouble getting this to work. I have executed steps for building and installing except insmod and added "ovs-vsctl set bridge br0 datapath_type=netdev". Any additional debugs which will help understand why its not working or have I missed anything? Following are some details...
