Here is bit description from DW QoS Eth data book(Part 19.6.2.2) bit7 IPCE: IP Payload Error When this bit is programmed, it indicates either of the following: 1).The 16-bit IP payload checksum (that is, the TCP, UDP, or ICMP checksum) calculated by the MAC does not match the corresponding checksum field in the received segment. 2).The TCP, UDP, or ICMP segment length does not match the payload length value in the IP Header field. 3).The TCP, UDP, or ICMP segment length is less than minimum allowed segment length for TCP, UDP, or ICMP.
