unresolved symbol

[Yang Hua]

I know what's wrong at last. 
The symbol numbers in netsyms.ver are incorrect. 
I did 'make clean' both in kernel directory and in netfilter directory.
After making both of them, I found it is OK.
I am not sure why there are wrong symbols. But it works well after all.

BTW, I am a graduate student in China. I am working on a research on
IPv6 and 
I am interested in netfilter. Do you have any plan on netfilter for
IPv6, Mr.Sussell?
