> Display and count some useful hot-path statistics. The usefulness is as
> follows:
> 
> - tx_restart: use to determine if the transmit ring size is too small or
>   if the transmit interrupt rate is too low.
> - rx_gro_dropped: use to count drops from GRO layer, which previously
> were
>   completely uncounted when occurring.
> - tx_busy: use to determine when the driver is miscounting number of
>   descriptors needed for an skb.
> - tx_timeout: as our other drivers, count the number of times we've reset
>   due to timeout because the kernel only prints a warning once per netdev.
> 
> Several of these were already counted but not displayed.
