> Count) register. However, the register value is already shown as
> rx_bytes and they always show the same value.

> Remove rx_long_byte_count as the Intel ethernet driver e1000e did in
> commit 0a939912cf9c ("e1000e: cleanup redundant statistics counter").
> 
> Tested on Intel Corporation I350 Gigabit Network Connection.
