      Description

      Scaling topology test is failing because of topology mismatch between onos and mininet

      And this is because onos fails to discover some of the links.
      The probably to reproduce this issue increases with the size of mininet topology. It's almost 100% reproducible with 3-node cluster and "torus,10,10" topology
