Description
Reserved
Receive TCO Packets Enabled
When this bit is set, it enables the receive flow from the wire to the
manageability block.
Reserved
Receive All Enable
When set, all packets are received from the wire and passed to the
manageability block.
Multicast Promiscuous
When set, all multicast filters pass L2 address filtering (same as the host
promiscuous multicast.
Enable Manageability Packets to Host Memory
This bit enables the functionality of the MANC2H register. When set, the
packets that are specified in the MANC2H registers are also forwarded to the
host memory, if they pass manageability filters.
Reserved
Enable Checksum Filtering to Manageability
When set, only packets that pass L3 and L4 checksums are sent to the
manageability block.
Enable IPv4 address Filters
When set, the last 128 bits of the MIPAF register are used to store four IPv4
addresses for IPv4 filtering. When cleared, these bits store a single IPv6
filter.
Fixed Next Type Enable
If set, only packets matching the net type defined by the NET_TYPE field
(bit 26 in this register) passes to manageability.
Net Type
0b = Pass only un-tagged packets.
1b = Pass only VLAN tagged packets.
Valid only if FIXED_NET_TYPE (bit 25) is set. Packet has to pass one MDEF/
RCV_ALL in order to be checked by this rule.
Reserved
4.4.3.10.4 Manageability Filters Valid – MFVAL (0x5824; RW)
The manageability filters valid registers indicate which filter registers contain a valid entry.
Reset – The MFVAL register is cleared on Internal Power On Reset or LAN_PWR_GOOD reset.
