For the 8168c and the later chips, our hardware engineer says that don't enable the RxFIFOOver of IntrMask and don't clear the RxFIFOOver of IntrStatus. The hardware will automatically escape Rx fifo full situation. Although you try to clear the RxFIFOOver of IntrStatus, maybe the bit wouldn't be cleared. Just disregard it.
