This is a gigabit ethernet driver for Topcliff PCH.
|
||||
Topcliff PCH is the platform controller hub that is used in Intel's
|
||||
general embedded platform.
|
||||
Topcliff PCH has Gigabit Ethernet interface.
|
||||
Using this interface, it is able to access system devices connected
|
||||
to Gigabit Ethernet.
|
||||
This driver enables Gigabit Ethernet function.
