4) Fragmentation
While it is important that such cases are dealt with correctly, they
are (annoyingly) rare: UDP-Lite is designed for optimising multimedia
performance over wireless (or generally noisy) links and thus smaller
- coverage lenghts are likely to be expected.

V) UDP-LITE RUNTIME STATISTICS AND THEIR MEANING
This displays UDP-Lite statistics variables, whose meaning is as follows.
- InDatagrams: Total number of received datagrams.
+ InDatagrams: The total number of datagrams delivered to users.
NoPorts: Number of packets received to an unknown port.
These cases are counted separately (not as InErrors).
VI) IPTABLES
There is packet match support for UDP-Lite as well as support for the LOG target.
