I think I am running Click configuration in kernel
space.  I used click-install to install my
configuration and a kernel module was inserted.

I compiled in user space, I put my element source code
under elemets\standard directory, but the object file
appeared in linuxmodule\ and I cannot figure out why. 
I think the compiler get the header file from
/usr/include instead of /usr/src/linux/include. 
That's why there are so many complaints from the
compiler.

Actually, I use AddressInfo to configure NIC, is there
a way to get local addresses from AddressInfo
elements.
