First, table 0 goes to table 1, then in table 1 there's a write_actions
that outputs to TABLE.

Then we execute the action set:

At the end of the flow table traversal by the action set, there's
another action set that outputs to port 1:

However, OVS doesn't execute action sets in a recursive manner (I don't
believe that's a reasonable thing to do), so that's where everything
ends.
