以太網接收寄存器相關需要深入研究，

如下：

    ETH_InitStructure.ETH_LoopbackMode = ETH_LoopbackMode_Disable;
    ETH_InitStructure.ETH_RetryTransmission = ETH_RetryTransmission_Disable;
    ETH_InitStructure.ETH_AutomaticPadCRCStrip = ETH_AutomaticPadCRCStrip_Disable;
    ETH_InitStructure.ETH_ReceiveAll = ETH_ReceiveAll_Disable;
    ETH_InitStructure.ETH_BroadcastFramesReception = ETH_BroadcastFramesReception_Enable;
    ETH_InitStructure.ETH_PromiscuousMode = ETH_PromiscuousMode_Disable;
    //ETH_InitStructure.ETH_MulticastFramesFilter = ETH_MulticastFramesFilter_Perfect;
    ETH_InitStructure.ETH_MulticastFramesFilter = ETH_MulticastFramesFilter_None;
    ETH_InitStructure.ETH_UnicastFramesFilter = ETH_UnicastFramesFilter_Perfect;
