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. This is so interesting for other drivers to in terms of code optimization. The second part (second

Yet another forward declaration I missed. Hopfully the last one ... A bunch of drivers want to know which tx queue triggered a timeout, and virtio wants to do the same. We actually have the info to hand, let's just pass it on to drivers. Note: tested with an experimental virtio patch by Julio. That patch itself isn't ready yet though, so not included. Other drivers compiled only.

Sorry about the churn, v10 was based on net - not on net-next by mistake. A bunch of drivers want to know which tx queue triggered a timeout, and virtio wants to do the same.
