Need open source PTPv2 client (something like ptp4l) for STM32F7. Did somebody encounter something similar for STM32F7? I have been searching but no luck... Need to imlement PTPv2 on STM32 microcontroller ASAP. Please, help...

I need a solution ideally based on stm32 + ethernet switch with PTP which has multiple (8 100 Mb fiber/copper ethernet ports). Could someone give me a clue for such a switch which will be suitable for stm32 or ideally  recommend me development board ...
