In normal operation, tx interrupts are not used and the sent descriptors are cleaned up either by rx interrupts or by the watchdog. The sole exception is when the tx queue is full. Then the tx interrupt is switched on because if no packages are received the wait time until the next watchdog run would be too long. > also you forget to undo the preps in vioif_populate_rx_mbufs > by calling a virtio_enqueue_abort if i understand this spaghetti > code correctly. Correct. Thanks.
