That's perfectly OK: before the stack can actually send the UDP packet, it has to know the target MAC address. Since it doesn't know it, yet, ARP request packets are sent. The stack should receive ARP response packets and (if ARP queueing is turned on), the original UDP packets should be sent (if ARP queueing is turned off, the old packets are not sent - udp_send() returns an error - but the next packets can be sent). So the question is: are there any ARP responses and if so, why doesn't the stack handle them. You should see the ARP response packets if they come from the same PC you are running wireshark on.
