Hi netif_rx is meant to be called from interrupts because it doesn't wake up ksoftirqd. For calling from outside interrupts, netif_rx_ni exists.
This patch fixes plip to use netif_rx_ni. It fixes the infamous error "NOHZ: local_softirq_panding 08" that happens on some machines with NOHZ and plip --- it is caused by the fact that softirq is pending and ksoftirqd is sleeping.
