+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#)Declare a ETH_HandleTypeDef handle structure, for example:
+ ETH_HandleTypeDef heth;
+
+ (#)Fill parameters of Init structure in heth handle
+
+ (#)Call HAL_ETH_Init() API to initialize the Ethernet peripheral (MAC, DMA, ...)
+
+ (#)Initialize the ETH low level resources through the HAL_ETH_MspInit() API:
+ (##) Enable the Ethernet interface clock using
+ (+++) __HAL_RCC_ETHMAC_CLK_ENABLE();
+ (+++) __HAL_RCC_ETHMACTX_CLK_ENABLE();
+ (+++) __HAL_RCC_ETHMACRX_CLK_ENABLE();
+
+ (##) Initialize the related GPIO clocks
+ (##) Configure Ethernet pin-out
+ (##) Configure Ethernet NVIC interrupt (IT mode)
+
+ (#)Initialize Ethernet DMA Descriptors in chain mode and point to allocated buffers:
+ (##) HAL_ETH_DMATxDescListInit(); for Transmission process
+ (##) HAL_ETH_DMARxDescListInit(); for Reception process
+
+ (#)Enable MAC and DMA transmission and reception:
+ (##) HAL_ETH_Start();
+
+ (#)Prepare ETH DMA TX Descriptors and give the hand to ETH DMA to transfer
+ the frame to MAC TX FIFO:
+ (##) HAL_ETH_TransmitFrame();
+
+ (#)Poll for a received frame in ETH RX DMA Descriptors and get received
+ frame parameters
+ (##) HAL_ETH_GetReceivedFrame(); (should be called into an infinite loop)

+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#)Declare a ETH_HandleTypeDef handle structure, for example:
+ ETH_HandleTypeDef heth;
+
+ (#)Fill parameters of Init structure in heth handle
+
+ (#)Call HAL_ETH_Init() API to initialize the Ethernet peripheral (MAC, DMA, ...)
+
+ (#)Initialize the ETH low level resources through the HAL_ETH_MspInit() API:
+ (##) Enable the Ethernet interface clock using
+ (+++) __HAL_RCC_ETHMAC_CLK_ENABLE();
+ (+++) __HAL_RCC_ETHMACTX_CLK_ENABLE();
+ (+++) __HAL_RCC_ETHMACRX_CLK_ENABLE();
+
+ (##) Initialize the related GPIO clocks
+ (##) Configure Ethernet pin-out
+ (##) Configure Ethernet NVIC interrupt (IT mode)
+
+ (#)Initialize Ethernet DMA Descriptors in chain mode and point to allocated buffers:
+ (##) HAL_ETH_DMATxDescListInit(); for Transmission process
+ (##) HAL_ETH_DMARxDescListInit(); for Reception process
+
+ (#)Enable MAC and DMA transmission and reception:
+ (##) HAL_ETH_Start();
+
+ (#)Prepare ETH DMA TX Descriptors and give the hand to ETH DMA to transfer
+ the frame to MAC TX FIFO:
+ (##) HAL_ETH_TransmitFrame();
+
+ (#)Poll for a received frame in ETH RX DMA Descriptors and get received
+ frame parameters
+ (##) HAL_ETH_GetReceivedFrame(); (should be called into an infinite loop)
+
+ (#) Get a received frame when an ETH RX interrupt occurs:
+ (##) HAL_ETH_GetReceivedFrame_IT(); (called in IT mode only)
+
+ (#) Communicate with external PHY device:
+ (##) Read a specific register from the PHY
+ HAL_ETH_ReadPHYRegister();
+ (##) Write data to a specific RHY register:
+ HAL_ETH_WritePHYRegister();
+
+ (#) Configure the Ethernet MAC after ETH peripheral initialization
+ HAL_ETH_ConfigMAC(); all MAC parameters should be filled.
+
+ (#) Configure the Ethernet DMA after ETH peripheral initialization
+ HAL_ETH_ConfigDMA(); all DMA parameters should be filled.
+
+ -@- The PTP protocol and the DMA descriptors ring mode are not supported
+ in this driver

+ * @brief ETH HAL module driver.
+ * This file provides firmware functions to manage the following

+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral Control functions
+ * + Peripheral State and Errors functions

+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#)Declare a ETH_HandleTypeDef handle structure, for example:
+ ETH_HandleTypeDef heth;
+
+ (#)Fill parameters of Init structure in heth handle
+
+ (#)Call HAL_ETH_Init() API to initialize the Ethernet peripheral (MAC, DMA, ...)
+
+ (#)Initialize the ETH low level resources through the HAL_ETH_MspInit() API:
+ (##) Enable the Ethernet interface clock using
+ (+++) __HAL_RCC_ETHMAC_CLK_ENABLE();
+ (+++) __HAL_RCC_ETHMACTX_CLK_ENABLE();
+ (+++) __HAL_RCC_ETHMACRX_CLK_ENABLE();
+
+ (##) Initialize the related GPIO clocks
+ (##) Configure Ethernet pin-out
+ (##) Configure Ethernet NVIC interrupt (IT mode)
+
+ (#)Initialize Ethernet DMA Descriptors in chain mode and point to allocated buffers:
+ (##) HAL_ETH_DMATxDescListInit(); for Transmission process
+ (##) HAL_ETH_DMARxDescListInit(); for Reception process
+
+ (#)Enable MAC and DMA transmission and reception:
+ (##) HAL_ETH_Start();
+
+ (#)Prepare ETH DMA TX Descriptors and give the hand to ETH DMA to transfer
+ the frame to MAC TX FIFO:
+ (##) HAL_ETH_TransmitFrame();
+
+ (#)Poll for a received frame in ETH RX DMA Descriptors and get received
+ frame parameters
+ (##) HAL_ETH_GetReceivedFrame(); (should be called into an infinite loop)
+
+ (#) Get a received frame when an ETH RX interrupt occurs:
+ (##) HAL_ETH_GetReceivedFrame_IT(); (called in IT mode only)
+
+ (#) Communicate with external PHY device:
+ (##) Read a specific register from the PHY
+ HAL_ETH_ReadPHYRegister();
+ (##) Write data to a specific RHY register:
+ HAL_ETH_WritePHYRegister();
+
+ (#) Configure the Ethernet MAC after ETH peripheral initialization
+ HAL_ETH_ConfigMAC(); all MAC parameters should be filled.
+
+ (#) Configure the Ethernet DMA after ETH peripheral initialization
+ HAL_ETH_ConfigDMA(); all DMA parameters should be filled.
+
+ -@- The PTP protocol and the DMA descriptors ring mode are not supported
+ in this driver
