82571/82572 Specification Update
6. Specification Changes
1.
Operation of the SMBus at 1 MHz is not supported. Operation at the standard SMBus frequency (400
kHz) is not affected and is supported. The operation frequency is set by the EEPROM.
2.
The extended Rx and Rx write-back descriptors are affected. This information supercedes the
information in the PCIe Family of Gigabit Ethernet Controllers Software Developer’s Manual, Section
3.2.6.5.
The following tables reflect the changes:
PKTTYPE (bit 19:16):
The PKTTYPE field defines the type of the packet that was detected by the device. It tries to find the
most complex match until it locates the most common one, as shown in the Packet Type table below:

Payload does not mean raw data, but can be also an unsupported header.
If there is NFS header in the packets, it can be seen in the packet type field.
