operating environment and can be viewed on the docs.sun.com website.

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 provides the PCI interface, Media
Access Control (MAC) functions, and Physical Code Sublayer (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
the section, "Setting the Autonegotiation Mode" on page 37. 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.
