In the status response frame of the EPL(Powerlink) protocol, the field "Device
profile specific" (Offset 0x1a, includes the Ethernet frame) has the wrong
length. It is displayed as a 8 byte field, but in fact it has only a size of 6
byte. Compare e.g. with packet number 1124 in dump. Because of this the folling
data(ErrorCodeList) is displayed wrong.
