tests: Test learned flow idle timeouts.
Browse files Browse the repository at this point in the history 
The previous tests would check that a single learned flow had its stats
correctly attributed to the right interfaces and flows. These new tests
take it a step further by causing two different learned flows to be
created, and checking the stats are correct. This is done for rules that
are learned with idle and hard timeouts.
