Chapter 3 Configuring Driver Parameters 47
The following Ethernet properties (TABLE3-15) are derived from the intersection ofdevice capabilities and the link partner capabilities.
TABLE3-15 describes the current Ethernet link properties.
TABLE3-16 describes the read-only Media Independent Interface (MII) capabilities.
These parameters define the capabilities of the hardware. The Gigabit MediaIndependent Interface (GMII) supports all of the following capabilities.
