      IPoIB: Don't turn on carrier for a non-active port · 5ee95120
      Moni Shoua authored
      Multicast joins can succeed even if the IB port is down.  This happens
      when the SM runs on the same port with the requesting port.  However,
      IPoIB calls netif_carrier_on() when the join of the broadcast group
      succeeds, without caring about the state of the IB port.  The result
      is an IPoIB interface in RUNNING state but without an active IB port
      to support it.
      
      If a bonding interface uses this IPoIB interface as a slave it might
      not detect that this slave is almost useless and failover
      functionality will be damaged.  The fix checks the state of the IB
      port in the carrier_task before calling netif_carrier_on().
