Some Ethernet PHYs contain a simple packet generator. This can be useful for bringing up new devices, trying to determine if a problem lies in the MAC-PHY connection or PHY-Socket. Also, the PHY generators can generate invalid packets, which is hard to do in software.
Add support ethtool(1) and wire up the Marvell PHY packet generator.
