Determines if packets that have passed decision filter 2 are also forwarded to the
host OS.
Determines if packets that have passed decision filter 3 are also forwarded to the
host OS.
Determines if packets that have passed decision filter 4 are also forwarded to the
host OS.
Determines if broadcast packets are also forwarded to the host OS.
Determines if unicast packets are also forwarded to the host OS.
Determines if multicast packets are also forwarded to the host OS.
All manageability filters are controlled by the BMC only and not by the LAN device driver.
The BMC enables these filters by issuing the Update Management Receive Filter Parameters command
(see Section 5.3.10.1.6) with the parameter of 0x60.
5.3.4 SMBus Transactions
This section gives a brief overview of the SMBus protocol.
Following is an example for a format of a typical SMBus transaction:

The top row of the table identifies the bit length of the field in a decimal bit count. The middle row
(bordered) identifies the name of the fields used in the transaction. The last row appears only with
some transactions, and lists the value expected for the corresponding field. This value can be either
hexadecimal or binary.
The shaded fields are fields that are driven by the slave of the transaction. The un-shaded fields are
fields that are driven by the master of the transaction. The SMBus controller is a master for some
transactions and a slave for others. The differences are identified in this section.
Shorthand field names are listed in Table 5-2 and are fully defined in the SMBus specification:
