      Description of problem:

      When running automated regression VRF SRIOV DHCP test cases Looks like a degradation bug. DHCP client pod stuck in ContainerCreating state.  The the server and client pods are configured with secondary VRF interfaces. The two VRFs have overlapping IP address ranges. It takes up to 7 mins for both server and client pods to recieve IP allocation from the dhcp server.

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

      OCP 4.13.11

      How reproducible:

      Run cnf-gotest 

      Steps to Reproduce:

      1. BM cluster running OCP 4.13.11
      2. Run VRF sriov cnf-gotests
      3.
      

      Actual results:

      Pod with overlapping VRF IP addresses is stuck in ContainerCreating
      Timed out after 120.001s.
      Expected
          <v1.PodPhase>: Pending
      to equal
          <v1.PodPhase>: Running

      Expected results:

      Container is meant to receive an IP address from the dhcp server and go to running state.
