      Description

      Somehow, o2iblnd in latest master branch (225e7b8) is looking for wrong IB interface.

      # cat /etc/modprobe.d/lustre.conf 
      options lnet networks="o2ib0(ib0)"
      
      # modprobe lustre
      modprobe: ERROR: could not insert 'lustre': Network is down
      

      they are trying to use 'eth0' insetad of ib0. eth0 is notihng configured for o2iblnd though.
