1. When set, this bit actually indicates the presence of a manageability entity. Therefore, it prevents the PHY
Management Control to Host Register - MANC2H (0x5860; RW)
The MANC2H register enables routing of manageability packets to the host based on
the decision filter that routed it to the manageability micro-controller. Each
Manageability Decision Filter (MDEF) has a corresponding bit in the MANC2H register.
When an MDEF routes a packet to manageability, it also routes the packet to the host if
the corresponding MANC2H bit is set and if the EN_MNG2HOST bit is set. The
EN_MNG2HOST bit serves as a global enable for the MANC2H bits.

from being powered down while in power saving states. When this bit is cleared, the PHY might be powered
down, so transmit flow might not be possible as well. It's therefore recommended to set this bit when the BMC
needs to enable either receive or transmit.

Value
Receive All Enable
When set, all received packets that passed L2 filtering are directed to
the manageability block. When RCV_ALL is set to 1b, no other
manageability filters should be set - all traffic is directed to the
manageability subsystem.
Receive All Multicast
When set, all received multicast packets pass L2 filtering (similar as
host promiscuous multicast). These packets can be directed to the
manageability block by a one of the decision filters. Broadcast packets
are not forwarded by this bit.
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 forwarded
to host memory too, if they pass manageability filters.
Reserved
Enable Xsum Filtering to Manageability
When this bit is set, only packets that passes L3 and L4 checksum are
sent to the manageability block.
Reserved
Fixed Net Type
If set, only packets matching the net type defined by the NET_TYPE
field passes to manageability. Otherwise, both tagged and un-tagged
packets can be forwarded to manageability engine.
NET TYPE:
0b = Pass only un-tagged packets.
1b = Pass only VLAN tagged packets.
Valid only if FIXED_NET_TYPE is set .
Reserved
Disable IP Address Checking for ARP Packets
When set, the IP address is not checked for a match on ARP packets.
When cleared, an ARP request packet is passed to the MC only if the
IP filter was configured and there is a match with one of the four
programmed IPv4.
This bit affects manageability filtering only. It does not affect wake-up
ARP.
