Configuring the Driver Parameters

This section provides an overview of the capabilities of the GigabitEthernet ASIC used in the adapters, lists the available ge driver parameters, and describes how to configure these parameters.

The ge driver controls the Sun GigabitEthernet adapter devices. The Sun GigabitEthernet device is identified as network with the model property SUNW,sbus-gemor SUNW,pci-gemnode. The ge driver is attached to the device with the compatible property pci108e,2bad for the Sun GigabitEthernet/P adapter or SUNW,sbus-gemfor the Sun GigabitEthernet/S adapter. You can manually configure the parameters to customize each Sun GigabitEthernet adapter in your system.

GigabitEthernet MAC

The GigabitEthernet MAC (GEM) provides 1000BASE-SX networking interfaces. The driver automatically sets the link speed to 1000 Mbps and conforms to the IEEE 802.3z Ethernet standard. The GEM PCI ASIC provide the PCI interface, Media Access Control (MAC) functions, and Physical Code Sublayer (PCS) functions. The GEM SBus ASIC provides the SBus interface, MAC functions, and PCS functions. The External SERDES, which connects the 1000BASE-SX Compliant SC connector to the ASIC, provides the physical layer functions.

The GEM MAC and PCS are capable of all the operating speeds and modes listed in “Autonegotiation Mode” on page 13. The PCS performs autonegotiation with the remote end of the link (link partner) to select a common mode of operation.

The PCS also supports a forced mode of operation. You can select the speed and mode by creating a ge.conf file.
