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?
