Ethernet MAC (EMAC) Registers
Description
When this bit is set, 2-tuple hashes are enabled
for IPV4 packets.
–
This bit disables the fix that EMAC stage fsm
drops a packet if incoming packet's DA has a
partial match in both perfect match address and
Pause Multicast address.
When set, reception of broadcast frames is
disabled
If set, forces Receive MAC to keep the VLAN tag
in the frame.
This is for debugging purpose only and should be
reset during normal operation
When set, no CRC check by receive MAC on
incoming frames.
Also, allows the reception of packets received
with RXERR on MII/GMII.
When set, no source address or MC hashing
checking will be performed on incoming frames.
All frames will be accepted.
If set, 802.2 length checking is done on LLC
frames.
If set, MAC accepts packets less than 64 bytes.
–
If set, MAC forwards pause frame to host buffer.
–
Enable automatic processing of 802.3x flow
control frames.
This bit is orthogonal to the Keep Pause bit.
This bit controls whether the Receive MAC state
machine is active or not.
When set to 0, it completes the current operation
and cleanly halts. Until it is completely halted, it
remains 1 when read.
When this bit is set to 1, the Receive MAC state
machine will be reset.
This is a self-clearing bit.
