Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths

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.
