"Using Open vSwitch without kernel support" related to this?

To be specific, " On Linux, when a physical interface is in use by the
userspace
datapath, packets received on the interface still also pass into the
kernel TCP/IP stack.  This can cause surprising and incorrect
behavior.  You can use "iptables" to avoid this behavior, by using it
to drop received packets.  For example, to drop packets received on
eth0:
 
     iptables -A INPUT -i eth0 -j DROP
     iptables -A FORWARD -i eth0 -j DROP
