Hi Alessio, you can take a look at BFD code which
a.) creates and sends its own UDP packets - bfd_main.c - bfd_send_periodic() creates, encapsulates (UDP) and sends a packet out b.) loops back packets received - bfd_udp.c - bfd_udp_echo_input() I'm not sure what's your use case, whether you are trying to reuse existing buffer, but one of these should fit it.
