      Description of problem:

      When running the cnf-feature-deploy VRF test case withover lapping IPs on the OCP primary interface traffic does not flow over any of the secondary interfaces VRF and non-VRF. This test case fails on the Intel X810 card but passes on the Mellanox Connect-X5 card. 

      Version-Release number of selected component (if applicable):


      How reproducible:


      Steps to Reproduce:

      1. Deploy OCP 4.14-rc1 on BM cluster with SRIOV Intel X710 card
      2. Run VRF Overlapping CNF-test

      Actual results:

        [FAILED] Unexpected error:      <*fmt.wrapError | 0xc0005d24e0>:       remote command [ping -I red -c5] error [command terminated with exit code 1]. output [ping: Warning: source address might be selected on device other than red.      PING ( from red: 56(84) bytes of data.      From icmp_seq=1 Destination Host Unreachable      From icmp_seq=2 Destination Host Unreachable      From icmp_seq=3 Destination Host Unreachable      From icmp_seq=4 Destination Host Unreachable      From icmp_seq=5 Destination Host Unreachable            --- ping statistics ---      5 packets transmitted, 0 received, +5 errors, 100% packet loss, time 4107ms      pipe 3      ]      {

      Expected results:

      ping -I red -c5 should be successful on both Intel X710 and MLX Connect-X5 card

      Additional info:

      The test also fails with 4.13.11
