commit 42106d4696aaa8e91e458783b15c90335ff5f7e3 Author: Maciej Józefczyk <[email protected]> Date: Fri Jan 17 15:08:27 2020 +0000 Don't fail if VIP already exist or has been deleted before Sometimes there is a race condition on creation of VIP port or deleting it that ends with exception and blocks LB stack creation / deletion. Because for now we don't have running master branch for OVN provider driver this change will be applied first on stable/train in networking-ovn tree and then cherry-picked.
