+This is a FreeeRTOS+TCP driver that works for both STM32F4xx and STM32F7xx parts.
+
+The code of stm32fxx_hal_eth.c is based on both drivers as provided by ST.
+
+These modules should be included:
+
+    NetworkInterface.c
+	stm32fxx_hal_eth.c
+
+It is assumed that one of these words are defined:
+
+	STM32F7xx
+	STM32F407xx
+	STM32F417xx
+	STM32F427xx
+	STM32F437xx
+	STM32F429xx
+	STM32F439xx
+
+The driver has been tested on both Eval and Discovery boards with both STM32F4 and STM32F7.
