completion status is received, the System Error bit in the PCI configuration space is set.
If the system errors are enabled in configuration space, a system error is indicated on
the PCI host bus.
3.3.3 Ethernet Interface
The integrated GbE controller provides a complete CSMA/CD function supporting IEEE
802.3 (10 Mb/s), 802.3u (100 Mb/s) implementations. It also supports the IEEE 802.3z
and 802.3ab (1000 Mb/s) implementations. The device performs all of the functions
required for transmission, reception, and collision handling called out in the standards.
The mode used to communicate between Intel® Xeon® Processor D-1500 Product
Family and the Intel® Ethernet Network Connection I127LM/V Platform LAN Connect
Device supports 10/100/1000 Mb/s operation, with both half- and full-duplex operation
at 10/100 Mb/s, and full-duplex operation at 1000 Mb/s.
3.3.3.1 Intel
®
Ethernet Network Connection I127LM/V Platform LAN Connect
Device Interface
The integrated GbE controller and the Intel
®
Ethernet Network Connection I127LM/V
Platform LAN Connect Device communicate through the PCIe and SMLink interfaces. All
integrated GbE controller configuration is performed using device control registers
mapped into system memory or I/O space. The Platform LAN Connect Device is
configured using the PCI Express* or SMBus interface.
The integrated GbE controller supports various modes as listed in Ta b l e 3- 4.
3.3.4 PCI Power Management
The integrated GbE controller supports the Advanced Configuration and Power Interface
(ACPI) specification as well as Advanced Power Management (APM). This enables the
network-related activity (using an internal host wake signal) to wake up the host.
The integrated GbE controller contains power management registers for PCI and
supports D0 and D3 states. PCIe* transactions are only allowed in the D0 state, except
for host accesses to the integrated GbE controller’s PCI configuration registers.
3.3.4.1 Wake Up
The integrated GbE controller supports two types of wake-up mechanisms:
1. Advanced Power Management (APM) Wake Up
2. ACPI Power Management Wake Up
