Scenario:
==========
1.Create Network (e.g 7.1.1.0/24) on openstack
2.Create Virtual Router and assign step-1 network(i.e 7.1.1.0/24) to Router Interface
3.Verify the br-int OF flow entries
4.Delete 7.1.1.0/24 association from Router Interface
5.Verify the br-int OF flow entries [you can see stale OF entries of step-2]
6.Delete 7.1.1.0/24 Network itself.
7.Verify the br-int OF Flow entries [still OF stale entries present]
