33   Several applications have been ported successfully to UDP-Lite. Ethereal
34   (now called wireshark) has UDP-Litev4/v6 support by default.
36   Porting applications to UDP-Lite is straightforward: only socket level and
43   UDP-Lite provides a connectionless, unreliable datagram service and hence
44   uses the same socket type as UDP. In fact, porting from UDP to UDP-Lite is
56   With just the above change you are able to run UDP-Lite services or connect
57   to UDP-Lite servers. The kernel will assume that you are not interested in
58   using partial checksum coverage and so emulate UDP mode (full coverage).
