      While current linux-2.6 kernel doesnt emit this warning, bug is latent
      and might cause unexpected failures.
      
      ip_dev_loopback_xmit() runs in process context, preemption enabled, so
      must call netif_rx_ni() instead of netif_rx(), to make sure that we
      process pending software interrupt.
      
      Same change for ip6_dev_loopback_xmit()
