Why not? I also noticed that...
As far as I know, after receiving a packet, the datapath will send a message
to the ovs-vswitchd stating that there is no rule matching that packet. Upon
receiving this "missed flow message", ovs-vswitchd can check if the paket
ip_dst matches one of its local interfaces' addresses and is able to answer
the question telling the datapath to send the packet to the running kernel
IP stack. Is there any rule prohibiting this behavior?
