to Gigabit Ethernet.
This driver enables Gigabit Ethernet function.
+ This driver also can be used for OKI SEMICONDUCTOR IOH(Input/
+ Output Hub), ML7223.
+ ML7223 IOH is for MP(Media Phone) use.
+ ML7223 is companion chip for Intel Atom E6xx series.
+ ML7223 is completely compatible for Intel EG20T PCH.
