Management MAC Address (Data Bytes 7:2)
Ignored if the CBDM bit is not set. This MAC address is used to configure the dedicated
MAC address. This MAC address is also used when CBDM bit is set in subsequent short
versions of this command.
Management IP Address (Data Bytes 11:8)
The 82574L does not support an SMBus ARP response. As a result, the Management IP
address field is ignored in the 82574L.
Asynchronous Notification SMBus Address (Data Byte 12)
This address is used for the asynchronous notification SMBus transaction and for direct
receive.
Interface Data (Data Byte 13)
Interface data byte used in asynchronous notification.
Alert Value Data (Data Byte 14)
Alert Value data byte used in asynchronous notification.
Force TCO Command
This command causes the 82574L to perform a TCO reset, if Force TCO reset is enabled
in the NVM. The force TCO reset clears the data path (Rx/Tx) of the 82574L to enable
the MC to transmit/receive packets through the 82574L. This command should only be
used when the MC is unable to transmit receive and suspects that the 82574L is
inoperable. This command also causes the LAN device driver to unload. It is
recommended to perform a system restart to resume normal operation.
The 82574L considers the Force TCO command as an indication that the operating
system is hung and clears the DRV_LOAD flag. The Force TCO Reset command format
is as follows:
