net-next works for me:

$ sudo aptitude install netsend
$ sudo tcpdump -n -ttt -vv -i lo > pcap.trace &
$ netsend udplite receive &
$ netsend udplite transmit /etc/fstab 127.0.0.1

$ cat pcap.trace
00:00:00.000000 IP (tos 0x0, ttl 64, id 30602, offset 0, flags [DF], proto unknown (136), length 40) 127.0.0.1 > 127.0.0.1:  udplite 20
00:00:00.000074 IP (tos 0x0, ttl 64, id 30603, offset 0, flags [DF], proto unknown (136), length 1125) 127.0.0.1 > 127.0.0.1:  udplite 1105


Kernel version? What is the output of strace?
