Filters
The RCV_ALL bit must be cleared if filtering is enabled.
In default mode, every packet that is directed to the MC, is not directed to host
memory. The MC can also configure the 82574 to direct certain manageability packets
to host memory by setting the EN_MNG2HOST bit in the MANC register. It then needs
to configure the 82574 to send manageability packets to the host (according to their
type) by setting the corresponding bits in the MANC2H register.
An example of packets that might be necessary to send to both the MC and host
operating system might be ARP requests. If the MC configures the manageability filters
to send ARP requests to the MC; however, does not also configure the settings to also
send them to the host, then the host operating system never receives ARP requests.
The MC controls the types of packets that it receives by programming the receive
manageability filters. Following is the list of filters that are accessible to the MC:
Available Filters
All filters are reset only on Internal Power On Reset. Register filters that enable filters
or functionality are also reset by firmware. These registers can be loaded from the NVM
following a reset.
2. Receive Filtering – In this mode only certain types of packets are directed to the
manageability block. The MC should set the RCV_TCO_EN bit together with the
specific packet type bits in the manageability filtering registers.
