[NET/IPv4]: update for udp.c only, to match 2.6.18-rc4-mm3
This is an update only, as the previous patch can not cope
with recent changes to udp.c (all other files remain the same).
Up-to-date, complete patches can always be taken from
http://www.erg.abdn.ac.uk/users/gerrit/udp-lite/files/udplite_linux.tar.gz

Huh, what was this one? trailing whitespace? Can you leave this for
another cset doing just the reformatting?

I guess these comments can go as well, as one can quickly realise the
functions handles UDP lite with all the "IS_UDPLITE(sk)" calls and
"is_{udp}lite" variables :-)
