      Description of problem:

      As of this change to Ovn-Kubernetes (https://github.com/openshift/ovn-kubernetes/commit/63f398bebbed604c74f9a0010c74849d955074c9) node port service traffic fails when run in a DPU mode 2-cluster set up.
      
      This is due to the switch from using the l3gatewayAddresses to hostAddresses here: https://github.com/ovn-org/ovn-kubernetes/pull/3557/files#diff-b61468c0028d28eb0e1060d24f53f28b6482acfbfd0cf5c15f9c23c3fd8c9f91R469
      
      In a 2-cluster design, hostAddresses will be the address of the bluefield node running on behalf of the tenant, rather than the tenant node IP which results in this failure.

       

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

       

      How reproducible:

      Everytime

      Steps to Reproduce:

      1. Deploy a cluster with BF-2 in DPU mode
      2. Add a new node port Service to the cluster
      3. Try to use the node port service to pass traffic in the tenant cluster (x86)
      

      Actual results:

      TCP-05-b-pod2nodePortSvc-podBackend-diffNode.txt    0 bits/sec    0    No Packets Detected On Client Or Server VF Reps    Fail    0 bits/sec    0    No Packets Detected On Client Or Server VF Reps    Fail

      Expected results:

      TCP-05-b-pod2nodePortSvc-podBackend-diffNode.txt    3.55Gbits/sec    0    No Packets Detected On Client Or Server VF Reps    Pass    9.33Gbits/sec    0    No Packets Detected On Client Or Server VF Reps    Pass
