在 drivers/stm32f4xx_eth.c 里

```
void rt_hw_stm32_eth_init(void)
{
    /* PHY RESET: PC0 */
    {
        GPIO_InitTypeDef GPIO_InitStructure;

GPIO_InitStructure.GPIO_Mode  = GPIO_Mode_OUT;
        GPIO_InitStructure.GPIO_Speed = GPIO_Speed_2MHz;
        GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;
        GPIO_InitStructure.GPIO_PuPd  = GPIO_PuPd_NOPULL;

RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOC, ENABLE);

GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
        GPIO_Init(GPIOC, &GPIO_InitStructure);

GPIO_ResetBits(GPIOC, GPIO_Pin_0);
        rt_thread_delay(2);
        GPIO_SetBits(GPIOC, GPIO_Pin_0);
        rt_thread_delay(2);
    }

GPIO_Configuration();
    NVIC_Configuration();

stm32_eth_device.ETH_Speed = ETH_Speed_100M;
    stm32_eth_device.ETH_Mode  = ETH_Mode_FullDuplex;

/* OUI 00-80-E1 STMICROELECTRONICS. */
    stm32_eth_device.dev_addr[0] = 0x00;
    stm32_eth_device.dev_addr[1] = 0x80;
    stm32_eth_device.dev_addr[2] = 0xE1;
    /* generate MAC addr from 96bit unique ID (only for test). */
    stm32_eth_device.dev_addr[3] = *(rt_uint8_t*)(0x1FFF7A10+4);
    stm32_eth_device.dev_addr[4] = *(rt_uint8_t*)(0x1FFF7A10+2);
    stm32_eth_device.dev_addr[5] = *(rt_uint8_t*)(0x1FFF7A10+0);

stm32_eth_device.parent.parent.init       = rt_stm32_eth_init;
    stm32_eth_device.parent.parent.open       = rt_stm32_eth_open;
    stm32_eth_device.parent.parent.close      = rt_stm32_eth_close;
    stm32_eth_device.parent.parent.read       = rt_stm32_eth_read;
    stm32_eth_device.parent.parent.write      = rt_stm32_eth_write;
    stm32_eth_device.parent.parent.control    = rt_stm32_eth_control;
    stm32_eth_device.parent.parent.user_data  = RT_NULL;

stm32_eth_device.parent.eth_rx     = rt_stm32_eth_rx;
    stm32_eth_device.parent.eth_tx     = rt_stm32_eth_tx;

/* init tx semaphore */
    rt_sem_init(&tx_wait, "tx_wait", 0, RT_IPC_FLAG_FIFO);

/* register eth device */
    eth_device_init(&(stm32_eth_device.parent), "e0");

/* start phy monitor */
    {
        rt_thread_t tid;
        tid = rt_thread_create("phy",
                               phy_monitor_thread_entry,
                               RT_NULL,
                               512,
                               RT_THREAD_PRIORITY_MAX - 2,
                               2);
        if (tid != RT_NULL)
            rt_thread_startup(tid);
    }
}
INIT_PREV_EXPORT(rt_hw_stm32_eth_init);

```

自动初始化的，不需要自己调用初始化
env 里选择之后还要 scons --target=mdk5 -s 生成工程才可以
