problems with udp header compression

[Simon Vincent <simon.vincent@xsilon.com>]

I think I have stumbled across a bug in the udp header compression or 
possibly in a higher layer of the network stack.

If I send a UDP message using a RAW socket[0] the src and dest port 
numbers get corrupted on 802.15.4 devices. This does not occur on ethernet.

If I print out the udp source and destination ports in 
compress_udp_header they are incorrect. The function udp_hdr is not 
pointing at the udp header but actually the ip6 header.

If I send a UDP message using a normal UDP socket I do not have this 
problem.

Any ideas?
