ethtool v5: add autoneg advertise feature
adds the ability to change the advertised speed and duplex for a network interface. Previously, a network interface was only able to advertise all supported speed's and duplex's, or one individual speed and duplex. The feature allows the user to choose which supported speed's and duplex's to advertise by using the hex value.
