Detailed Description

Initialization and Configuration functions.

===============================================================================
            ##### Initialization and Configuration functions #####
 ===============================================================================
    [..]  This subsection provides a set of functions allowing to initialize and
          deinitialize the ETH peripheral:

      (+) User must Implement HAL_ETH_MspInit() function in which he configures
          all related peripherals resources (CLOCK, GPIO and NVIC ).

      (+) Call the function HAL_ETH_Init() to configure the selected device with
          the selected configuration:
        (++) MAC address
        (++) Media interface (MII or RMII)
        (++) Rx DMA Descriptors Tab
        (++) Tx DMA Descriptors Tab
        (++) Length of Rx Buffers

      (+) Call the function HAL_ETH_DeInit() to restore the default configuration
          of the selected ETH peripheral.
