Hello, Dmitry.

It’s 100% reproducible on virtual environment when we’re trying to deploy bonding in balance tcp or balance slb mode.
Tests related as a way to reproduce and a warning why these tests should fail when they’ll be merged.

As we can see problem is in rebalance procedure openvswitch tries to do since it started bonded interface. And in this time bonded interfaces stops to accept ARPs.

I just built openvswitch=1.9.3 which is LTS and wanna try it in the same case and try to descrease bond-rebalance-interval to 0(as Andrey K. suggested). If any of this will help - this could be the solution(but I'm really not sure bond-rebalance-interval=0 is a good way).
