From: Julio Faracco <jcfaracco at gmail.com> 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. To enable it, driver should have .ndo_tx_timeout implemented. This serie has two commits: In the past, we implemented a function to recover driver state when this kind of event
