Date: Sun, 6 Oct 2019 15:45:13 -0300 From: jcfaracco@...il.com To: netdev@...r.kernel.org Cc: mst@...hat.com, jasowang@...hat.com, davem@...emloft.net, virtualization@...ts.linux-foundation.org, linux-kernel@...r.kernel.org, dnmendes76@...il.com 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.
