Comment 1 Assaf Muller 2017-07-26 13:39:26 UTC 
This is fixed in openvswitch-2.6.1-11.git20161206.el7ost. We need to ensure RDO Newton and Ocata (Both on OVS 2.6) should be using that version.
Comment 2 Yatin Karel 2021-01-13 07:20:08 UTC 
Newton is EOL long ago so closing this bug as EOL, ocata+ have openvswitch-2.9.0+.
