ETH_UpdateDescriptor() uses ETH_RX_BUF_SIZE define instead of user supplied value #93

ETH_InitTypeDef has user supplied member RxBuffLen. In ETH_UpdateDescriptor() ETH_RX_BUF_SIZE is used instead: https://github.com/STMicroelectronics/STM32CubeF7/blob/6a3b9bb8d09839f365ba83a6cf5823ae5f5226db/Drivers/STM32F7xx_HAL_Driver/Src/stm32f7xx_hal_eth.c#L1234 https://github.com/STMicroelectronics/STM32CubeF7/blob/6a3b9bb8d09839f365ba83a6cf5823ae5f5226db/Drivers/STM32F7xx_HAL_Driver/Src/stm32f7xx_hal_eth.c#L1238

Also in ETH_DMARxDescListInit(): https://github.com/STMicroelectronics/STM32CubeF7/blob/6a3b9bb8d09839f365ba83a6cf5823ae5f5226db/Drivers/STM32F7xx_HAL_Driver/Src/stm32f7xx_hal_eth.c#L3000

This makes RxBuffLen cause confusion and makes it pretty useless as it has to be the same value as the define.
