Receive maximum frame length. These bits determine the maximum length of a received frame.
The reset value is 5EEh (1518). Frames with byte counts greater than RXMAXLEN are long
frames. Long frames with no errors are oversized frames. Long frames with CRC, code, or
alignment errors are jabber frames.
