Note: See Table 10-40 and Table 10-41 for description of the Multicast Extended Packet Reduction
format.
This command causes the NC to filter packets that have passed due to the multicast filter (MAC address
filters, as specified in the DMTF NC-SI).
The filtering of these packets are done such that the MC might add a logical condition that a packet
must match, or it must be discarded.
Note: Packets that might have been blocked can still pass due to other decision filters.
In order to disable multicast packet reduction, the MC should set all reduction filters to 0b. Following
such a setting, the NC must forward, to the MC, all packets that have passed the multicast filters
(global multicast filtering) as specified in the DMTF NC-SI.
The command shall overwrite any previously stored value.
10.6.3.7.9 Set Multicast Extended Packet Reduction Response (Intel Command 0x04,
Reduction Filter Index 0x11)
10.6.3.7.10 Set Broadcast Extended Packet Reduction Command (Intel Command 0x04,
Reduction Filter Index 0x12)
Note: See Table 10-40 and Table 10-41 for description of the Broadcast Extended Packet Reduction
format.
This command causes the NC to filter packets that have passed due to the broadcast filter (MAC
address filters, as specified in the DMTF NC-SI).
The filtering of these packets are done such that the MC might add a logical condition that a packet
must match, or it must be discarded.
