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

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. Michael S. Tsirkin (3): netdev: pass the stuck queue to the timeout

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. 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.
