Log Message:
pktq_dequeue(): Prevent packets from getting stuck beind barrier markers.
pktq_barrier() ensures that all packets enqueued before the barrier have
been dequeued before the barrier returns. However, previously, pktq_dequeue()
would return NULL when a barrier marker was encountered. If there were
packets queued up behind the marker and no additional softint were scheduled
for the pktqueue, those packets would end up stranded. pktq_dequeue() now
continues to the next slot after the marker, ensuring that processing can
continue after the barrier has been signaled.
