Checksum Errors Number of frames received with a CRC error.
Alignment Errors Number of frames received that did not contain an integral number
of octets. Normally a frame alignment error also causes a checksum
error on the frame.

FIFO buffer overflowed before obtaining the next DMA cycle.
Frames Too Long Number of frames received that exceed 1518 octets.
Receive Symbol Errors Number of errors in hardware MLT3 encoding. Indicates a
