Subject: [PATCH net-next v2 3/4] net: phy: display human readable PHY speed settings

Use a convenience function: phy_speed_to_str() which will display human
readable speeds.

Joe,

This is highly inspired from the version you sent to me, although
I renamed to phy_speed_to_str() for clarity as well as added the
unit suffix to each speed because your version would show:

Unknownmbps for instance.
