So as such UDP protocol makes no difference. One reason i can think is the use of multiple queues, or threads for transm= ission.

You have to re-order them when you receive them. For example using a sequen= ce number to index them into a circular buffer. Wireshark does not re-order UDP packets but merely shows them in the order = they were captured.
