需要根據Realtek820的數據手冊來配置PHY寄存器，以確保PHY與STM32F107VCT6芯片正確通信。您還需要實現`rx_descr_init`、`tx_descr_init`、`ETH_MACAddressConfig`、`ETH_SoftwareReset`、`ETH_GetSoftwareResetStatus`、`ETH_Init`、`ETH_DMAITConfig`、`ETH_DMATxDescChainInit`、`ETH_DMARxDescChainInit`、`ETH_DMATxDescInit`、`ETH_DMARxDescInit`等函數的具體實現。這些函數的具體實現取決于您的硬件配置和需求。
