Ethernet Receive Status register
Address: FF80 0014
The Ethernet Receive Status register contains the status for the last completed
receive buffer. The receive buffer complete bit (RXBR) is set in the Ethernet General
Status register when a receive frame is completed and the Receive Status register is
loaded. The lower 16 bits (D15:00) of the register are also loaded into the
StatusOrIndex field of the DMA buffer descriptor when using DMA mode.

RXSIZE
Receive buffer size in bytes
Provides the number of bytes contained in the next packet
to be read from the Ethernet receive FIFO.
When using DMA mode, the RXSIZE field is also copied
to the buffer length field in the DMA buffer descriptor.
Receive carrier event previously seen
Set to 1 to indicate that the MAC received a carrier event
from the Ethernet PHY since the last time a receive packet
event was recorded in this status register. The carrier event
is not associated with this particular packet.
A carrier event is defined as any activity on the receive
channel that does not result in a packet receive attempt.
