RX Data Buffer Pointer.
This is a 20-bit address pointer and DRBP [1:0] is always 2’b00.
Reserved.
PHY RX Error packet.
Read 1 means that an error occurred in receiving packets on MII interface.
Dribble packet.
Read 1 means the received packet is a dribble packet.
Over Buffer Length.
Read 1 means the received packet length > buffer maximum length.
Long packet.
Read 1 means the received packet length > maximum packet length.
Runt packet.
Read 1 means the received packet length < 64 Bytes.
CRC Error packet.
Read 1 means receiving a packet with CRC errors.
Multicast Hit.
It indicates that the received packet hits one of the hash-table bits.
MID table is hit.
Index of matched MIDx. These two bits indicate that the received packet hits one of the
MID groups.
The size of the received frame.
