If I had to do a project like this, I would do a 'git log -p' and then
reverse search for different actions in 'man ovs-ofctl'. Pick an
action that is similar to what you want to do, and see when it was
introduced and then look through all the patches in that series to get
a good picture. It should atleast be a starting point.
