Bits 9:0 – LFER[9:0]: Length Field Frame Errors

Length Field Frame Errors

This bit field counts the number of frames received that have a measured length shorter than that extracted from the length field (Bytes 13 and 14). This condition is only counted if the value of the length field is less than 0x0600, the frame is not of excessive length and checking is enabled by writing a '1' to the Length Field Error Frame Discard bit in the Network Configuration Register (GMAC_NCFGR.LFERD).
