Parameter
If the parameter that the MC sets is not supported by the 82574. The 82574 does not
NACK the transaction. After the transaction ends, the 82574 discards the data and
asserts a transaction abort status.
The Management Control command format is as follows:
Management Control Command Parameters/Content
Update Management Receive Filter Parameters
This command is used to set the manageability receive filters parameters. The
command is 0xCC. The first data byte is the parameter number and the data that
follows (length and content) are parameter specific as listed in management RCV filter
parameters.
If the parameter that the MC sets is not supported by the 82574, then the 82574 does
