Assignment of Decision Filters Bits
1. IP address checking on ARP packets is controlled by MANC.DIS_IP_ADDR_for_ARP.
In default mode, packets that are directed to the MC are 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 and then configuring
the 82574 to send manageability packets to the host, according to their type, by
setting the corresponding bits in the MANC2H register (one bit per each of the eight
decision rules).
All manageability filters are controlled by the MC only and not by the LAN device driver.
The Mng2Host register has the following structure:
L2 Unicast Address
Broadcast
Manageability VLAN
