> Subject: [Intel-wired-lan] [PATCH iwl-next v1] igbvf: add
> tx_timeout_count to ethtool statistics
>
> Add `tx_timeout_count` to ethtool statistics to provide visibility
> into transmit timeout events, bringing igbvf in line with other Intel
> ethernet drivers.
>
> Currently `tx_timeout_count` is incremented in igbvf_watchdog_task()
> and
> igbvf_tx_timeout() but is not exposed to userspace nor used elsewhere
> in the driver.
>
> Before:
> # ethtool -S ens5 | grep tx
> tx_packets: 43
> tx_bytes: 4408
> tx_restart_queue: 0
>
> After:
> # ethtool -S ens5 | grep tx
> tx_packets: 41
> tx_bytes: 4241
> tx_restart_queue: 0
> tx_timeout_count: 0
