rx_bits_phy is documented but not shown in ethtool --statistics. Make this value available via ethtool. rx_bits_phy is needed to calculate the Bit Error Ratio from rx_pcs_symbol_err_phy or rx_corrected_bits_phy. The existing rx_bytes_phy cannot be used for this calculation as it appears to be a counter above the PHY layer in the strict sense (i.e. traffic based).
