This series add two important features. One of them changes the
.ndo_tx_timeout to include an extra parameter to identify the stuck
queue. Many drivers are using a nester loop to identify which queue is
stooped/stucked. This is a redundant work since dev_watchdog is doing
exactly the same thing.
Driver virtio_net is not handling error events for TX provided by
dev_watchdog. This event is reached when transmission queue is having
problems to transmit packets. This could happen for any reason. To
enable it, driver should have .ndo_tx_timeout implemented.
