This wouldn't usually be configured by a user on a tunnel as a whole.
It would likely be applied selectively by ovs-vswitchd to certain
types of packets, such as liveness monitoring. Obviously, there is a
fair amount of additional wiring that can be done in userspace so my
plan here was to provide the mechanism and then increasingly take
advantage of it over time.
