Configuring e1000g Driver
Parameters
The e1000g device driver controls the Sun PCI-Express Dual Gigabit Ethernet
interfaces for Solaris x86 systems. You can manually set the e1000g device driver
parameters to customize each device in your system.
This chapter lists the available device driver parameters and describes how you can
set these parameters. Topics include:
■ “Hardware and Software Overview” on page 43
■ “Setting e1000g Driver Parameters” on page 44
■ “Sun PCI-Express Dual Gigabit Ethernet e1000g Driver Parameters” on page 50
Hardware and Software Overview
Each of the two e1000g channels provides 10BASE-T, 100BASE-TX, or 1000BASE-T
networking interfaces. The device driver automatically sets the link speed to 10, 100,
or 1000 Mbit/sec and conforms to the IEEE 802.3 Ethernet standard. The single
MAC/PHY chip provides the PCI-E interface and media access control (MAC)
functions.
The e1000g driver is capable of all the following operating speeds and modes:
■ 1000 Mbit/sec, full-duplex
■ 1000 Mbit/sec, half-duplex (not supported)
■ 100 Mbit/sec, full-duplex
■ 100 Mbit/sec, half-duplex
■ 10 Mbit/sec, full-duplex
■ 10 Mbit/sec, half-duplex
