|
|
The Ethernet controllers of the Marvel Kirkwood, Dove, Orion5x, MV78xx0,
|
|
Armada 370, Armada XP, Armada 7k and Armada 8k have an identical unit that
|
|
provides an interface with the MDIO bus. Additionally, Armada 7k and Armada
|
|
8k has a second unit which provides an interface with the xMDIO bus. This
|
|
driver handles these interfaces.
