      A multi-rail client can't setup lnet selftest to a router with multiple interface like this:

      # lctl list_nids 10.151.26.148@o2ib 10.151.25.170@o2ib 10.141.26.148@o2ib417 10.141.25.170@o2ib417

      Here is what peer show looks like

          - primary nid: 10.151.26.148@o2ib
      Multi-Rail: True
      peer ni:
        - nid: 10.141.26.148@o2ib417
          state: up
        - nid: 10.141.25.170@o2ib417
          state: NA
        - nid: 10.151.26.148@o2ib
          state: NA
        - nid: 10.151.25.170@o2ib
          state: NA
