• Network Interface transmission queue timeout, cause and recovery methods

  A network interface transmission queue is said to be timed-out, if it is in stopped condition and the time since last transmission from this queue has exceeded the threshold which is being dictated by the driver to the watchdog timer. A transmission queue is a collection of data packets waiting to be transmitted by the corresponding networking device. During the initialization of the network device, the transmission queues and the scheduler of the network device are activated via dev_activate(). At the same time, the method dev_watchdog_up() starts a timer to detect transmission problems. This timer calls the method dev_watchdog() every dev->watchdog_timeo ticks to check that the network adapter is working properly. In case the routine dev_watchdog() identifies that a transmission queue is disabled (netif_queue_stopped() returns TRUE) and the time since last frame transmission has exceeded the amount of time to wait (dev→watchdog_timeo), the timer’s handler invokes a routine registered by the device driver to perform recovery. Details of these handlers are being discussed in the further sections of this article.
