Presumably meaning "only one frame has the UDP header in it".

If you turn on the "Reassemble fragmented IP datagrams" option for the 
IP protocol (select Preferences from the Edit menu, open up the 
Protocols list in the Preferences dialog, select IP, and turn on that 
option; click "OK" to enable that option for the current Ethereal 
session, click "Save" and "OK" to make that the default option for all 
of your Ethereal sessions), Ethereal will attempt to reassemble IP 
packets that have been split up like that, and display the reassembled 
packet in the last fragment it sees.
