How long is your message? Ethernet requires a minimum of a 64 byte packet size to detect for collisions. You can drop the padding by reading the length from the IP header. Either that, or you're adding 10 to the uip_udp_send() argument.

Hi
When I send out a UDP message there is a 10 byte trailer after my message data. Why is this and can it be stopped ? Cheers... Steve
