acphy* at mii? phy ?
The acphy driver supports the Altima AC101, AC101L and AMD Am79c874 Net- PHY-1LP 10/100 Ethernet PHYs. These PHYs are often found on low-power Ethernet interfaces, such as MiniPCI interfaces found in laptops and embedded systems. The AMD 79c874 is a work-alike (most likely an OEM of the core) of the Altima part.
