Receive TCO Enable.
0b: Disable receive TCO packets.
1b: Enable Receive TCO packets.
Setting this bit enables all manageability receive filtering operations.
Enabling specific filters is done via the NVM or through special configuration
commands.
Note: When the RCV_EN bit is cleared, all receive TCO functionality is
disabled, not just the packets that are directed to the MC .
Receive All Enable.
0b: Disable receiving all packets.
1b: Enable receiving all packets.
Forwards all packets received over the wire that passed L2 filtering to the
external MC. This flag has no effect if bit 0 (Enable TCO packets) is
disabled.
Enable Status Reporting.
0b: Disable status reporting.
1b: Enable status reporting.
Reserved, Must be set to 0b
Notification Method. Define the notification method the 82574 uses.
00b: SMBUS Alert.
01b: Asynchronous notify.
10b: Direct receive.
11b: Not supported.
Reserved. Must be set to 1b.
Configure the MC Dedicated MAC Address.
Note: This bit should be 0b when the RCV_EN bit (bit 0) is not set.
0b: The 82574 shares the MAC address for MNG traffic with the host MAC
address, which is specified in NVM words 0x0-0x2.
1b: The 82574 uses the MC dedicated MAC address as a filter for incoming
receive packets.
The MC MAC address is set in bytes 2-7 in this command.
If a short version of the command is used, the 82574 uses the MAC address
configured in the most recent long version of the command in which the
CBDM bit was set.
When the dedicated MAC address feature is activated, the 82574 uses the
following registers to filter in all the traffic addressed to the MC MAC.
