ALGNERRC – Alignment Error Count Register
This register counts the number of receive packets with alignment errors (i.e. the
packet is not an integer number of bytes in length). In order for a packet to be counted
in this register, it must pass MAC address filtering (Broadcast or Individual-Address/
Multicast match) and must be 64B or greater (from <Destination Address> through
<CRC>, inclusively) in length. This register is valid only in GMII/MII mode, during 10/
100 Mbps operation.

RXERRC – Receive Error Count Register
This register counts the number of packets received in which RX_ER was asserted by
the PHY. In order for a packet to be counted in this register, it must pass MAC address
filtering (Broadcast or Individual-Address/Multicast match) and must be 64Bor greater
(from <Destination Address> through <CRC>, inclusively) in length.
