Jan Glauber d36deae750 qdio: extend API to allow polling ... Extend the qdio API to allow polling in the upper-layer driver. This is needed by qeth to use NAPI. To use the new interface the upper-layer driver must specify the queue_start_poll(). This callback is used to signal the upper-layer driver that is has initiative and must process the inbound queue by calling qdio_get_next_buffers(). If the upper-layer driver wants to stop polling it calls qdio_start_irq(). Since adapter interrupts are not completely stoppable qdio implements a software bit QDIO_QUEUE_IRQS_DISABLED to safely disable interrupts for an input queue. The old interface is preserved and will be used as is by zfcp.
