Correct, this would probably be a dropped packet.
You might expect packets to get re-ordered and even dropped when UDP is
sent out into the internet and taking different paths to get to the
But this is a direct point to point link. So, you might have one of
those less than perfect ethernet cards that on occasion, drop packets.
Some applications would re-send, some would silently drop (like skype),
USRP is just one of the few devices that reports the event.
