[PATCH RFC net-next 0/2] drivers: net: virtio_net: Implement
From: jcfaracco

From: Julio Faracco <jcfaracco@xxxxxxxxx>
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 happens, but the structure was to complex for virtio_net
that moment. Alternativelly, this skeleton should be enough for now.
For further details, see thread:

Patch 1/2:
Add statistic field for TX timeout events.
Patch 2/2:
Implement a skeleton function to debug TX timeout events.
