Bit 6: LCS: Late Collision Seen
It is set to indicate a late collision found during the frame
reception. Valid only when ED is set.
Bit 5: FT, Frame Type or IP packet
If CR15 bit 27 is set, this bit present the flag that this is IP
packet; otherwise
it is set to indicate the received frame is the Ethernet-type. It
is reset to indicate that the received frame is the EEE802.3-
type. Valid only when ED is set
Bit 4: RWT, Receive Watchdog Time-Out or TCP packet
If CR15 bit 27 is set, this bit present the flag that this is TCP
packet; otherwise
it is set to indicate the received watchdog time-out during the
frame reception. CR5<9> will also be set. Valid only when
ED is set.
Bit 3: PLE, Physical Layer Error or UDP packet
If CR15 bit 27 is set, this bit present the flag that this is UDP
packet; otherwise
it is set to indicate a physical layer error found during the
frame reception.
Bit 2: AE, Alignment Error
It is set to indicate the received frame ends with a non-byte
boundary.
Bit 1: CE, CRC Error
It is set to indicate the received frame ends with a CRC
error. Valid only when ED is set.
Bit 0: FOE, FIFO Overflow Error
This bit is valid only when End Descriptor is set. (ED = 1). It
is set to indicate a FIFO overflow error happens during the
frame reception.
