It looks like this patch is causing segfaults if you have existing
tunnels kernel tunnels and you change the datapath type to netdev
while the switch is running. For example, doing:
ovs-vsctl set bridge br0 datapath_type=netdev
Here is the backtrace:
Program terminated with signal 11, Segmentation fault.
