The Memory-Mapped I/O (MMIO) register descriptions for each of the four PCI 

functions of the integrated GbE controller are not in this document. The MMIO register 

descriptions are in the Intel

Controller Programmer’s Reference Manual (PRM). The PRM also provides details for 

each function’s IOADDR and IODATA registers located in I/O space that can be used to 

access the controller’s internal registers and memory units.

Network management is an important requirement in today's networked computer 

environment. Software-based management applications provide the ability to 

administer systems while the operating system is functioning in a normal power state, 

that is, when not in a pre-boot state or powered-down state. The System Management 

Bus (SMBus) Interface, Management Component Transport Protocol (MCTP) and the 

Network Controller Sideband Interface (NC-SI) fill the management void that exists 

when the operating system is not running or fully functional. This is accomplished by 

providing mechanisms by which manageability network traffic can be routed to and 

from a Management Controller (MC) such as a Baseboard Management Controller 

(BMC).

The Intel

Programmer’s Reference Manual (PRM) describes the supported management 

interfaces and supported hardware configurations for platform system management. It 

describes the interfaces to an external BMC, the partitioning of platform manageability 

among system components, and the functionality provided by in each platform 

configuration. For an overview of the hardware interface, see 

The SoC integrated GbE controller has the ability to route Ethernet traffic to the host 

operating system as well as the ability to send Ethernet traffic over the sideband 

interface to an external BMC. The term “Pass-Through” (PT) is used when referring to 

the process of the LAN Port sending and receiving Ethernet traffic over the sideband 

(SMBus or NC-SI) interface to/from the BMC. See
