Receive packet counter (A060 06A0)
Incremented for each received frame (including bad packets, and all unicast,
broadcast, and multicast packets).
Receive FCS error counter (A060 06A4)
Incremented for each frame received with a length of 64 to 1518 bytes, and
containing a frame check sequence (FCS) error. FCS errors are not counted for VLAN
frames that exceed 1518 bytes or for any frames with dribble bits.
Ignore this counter for RMII applications as it does not operate properly.
Receive multicast packet counter (A060 06A8)
Incremented for each good multicast frame with a length no greater than 1518 bytes
(non-VLAN) or 1522 bytes (VLAN), excluding broadcast frames. This counter does not
look at range/length errors.
Receive broadcast packet counter (A060 06AC)
Incremented for each good broadcast frame with a length no greater than 1518 bytes
(non-VLAN) or 1522 bytes (VLAN), excluding multicast frames. This counter does not
look at range/length errors.
