Management Control
This command is used to set generic manageability parameters. The parameters list is
shown in Management Control Command Parameters/Content. The command is 0xC1
stating that it is a Management Control command. The first data byte is the parameter
number and the data after words (length and content) are parameter specific as shown
in Management Control Command Parameters/Content.
If the parameter that the MC sets is not supported by the 82574L. The 82574L does not
NACK the transaction. After the transaction ends, the 82574L 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 82574L, then the 82574L
does not NACK the transaction. After the transaction ends, the 82574L discards the
data and asserts a transaction abort status.
The update management RCV receive filter parameters command format is as follows:

Data 2:
Bit 0: Set to indicate that the PHY link for this port should be
kept up throughout system resets. This is useful when the
server is reset and the MC needs to keep connectivity for a
manageability session.
Bit [7:1] Reserved.
0b: Disabled.
1b: Enabled.
