MRFCE MAC Receive Flow Control Enable
When this bit is set and the KSZ8841-PMQL is in Full Duplex mode, flow
control is enabled and the KSZ8841-PMQL will acknowledge a PAUSE
frame from MAC of the controller, the outgoing packets will be pending in
the transmit buffer until the PAUSE control timer expires.
This field has no meaning in half-duplex mode and should be programmed
to 0.
When this bit is cleared, no flow control is enabled.

MRM MAC Receive Multicast
When set, the MAC receive all multicast frames (including broadcast).

MRU MAC Receive Unicast
When set, the MAC receive unicast frames that match the 48-bit Station
Address of the MAC.

MRE MAC DMA Receive Error Frame
When set, the KSZ8841-PMQL will pass the errors frames received to the
host.
Error frames include runt frames, oversized frames, CRC errors.

MRA MAC DMA Receive All
When set, the KSZ8841-PMQL receives all incoming frames, regardless of
its destination address.

DMA Receive Multicast Hash-Table Enable
Setting this bit enables the RX function to receive multicast frames that pass
the CRC Hash filtering mechanism.

MRE MAC DMA RX Enable
When the bit is set, the DMA RX block is enabled and placed in a running
state. When reset, the receive process is placed in the stopped state after
completing the reception of the current frame. The stop transmission
command is effective only when the reception process is in the running
state.
MAC DMA Transmit Start Command Register (MDTSC Offset 0x0008)
This register is written by the CPU when packets in the data buffer need to be transmitted. The following table shows
the register bit fields.

When written with any value, the Transmit DMA checks for frames to
be transmitted. If no descriptor is available, the transmit process returns
to suspended state. If descriptiors are available, the transmit process
starts or resumes. This bit is self-clearing.
