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

From: Julio Faracco <jcfaracco@...il.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 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:
https://lkml.org/lkml/2015/6/23/691

Patch 1/2:
  Add statistic field for TX timeout events.

Patch 2/2:
  Implement a skeleton function to debug TX timeout events.

Julio Faracco (2):
  drivers: net: virtio_net: Add tx_timeout stats field
  drivers: net: virtio_net: Add tx_timeout function
