In summary, if a programmer increases the size of the SMBus fragment size in the
NVM, which is recommended for efficiency purposes, take care to ensure that the MC
implementation reflects this change and uses that fragment size to its fullest when
sending SMBus fragments.
Enable XSum Filtering
If XSum filtering is enabled, the MC does not need to perform the task of checking this
checksum for incoming packets. Only packets that have a valid XSum is passed to the
MC, all others are silently discarded.
This is a way to offload some work from the MC.
Still Having Problems?
If problems still exist, contact your field representative. Before contacting, be prepared

NC-SI Interface
The Network Controller Sideband Interface (NC-SI) is a DMTF industry standard
protocol for the sideband interface. NC-SI uses a modified version of the industry
standard RMII interface for the physical layer as well as defining a new logical layer.
The NC-SI specification can be found at the DMTF website at:
Overview
Terminology
The terminology in this document is taken directly from the NC-SI specification and is
as follows:
• The contents of status registers:
• A SMBus trace if possible
• A dump of the NVM image
— 0x5820
— 0x5860
— 0x5B54
— This should be taken from the actual 82574, rather than the NVM image
provided by Intel. Parts of the NVM image are changed after writing, such as
the physical NVM size. This information could be key in helping assist in solving
an issue.
