The patch adds driver interface for reading the config attributes from user provided buffer, and updates these values on nvm config flash partition. This is basically an expansion of our existing ethtool -f implementation. The management FW has exposed an additional method of configuring some of the nvram options, and this makes use of that. This implementation will come into use when newer FW files which contain configuration directives employing this API will be provided to ethtool -f.

rtl8169_free_rx_databuff is used in only one place, so let's inline it. We can improve the loop because rtl8169_init_ring zero's RX_databuff before calling rtl8169_rx_fill, and rtl8169_rx_fill fills Rx_databuff starting from index 0.
