can't get packets: not compiled with polling extensions

I am trying to test the UDP generation Click configuration (the one in the
example named "udpgen.click"). However, when I run the click from the
kernel mode, I got the following error:
Dec 8 16:59:42 am14-03 kernel: [ 4559.112683] udpgen.click:30: While
initializing 'u/pd :: PollDevice':
Dec 8 16:59:42 am14-03 kernel: [ 4559.112686] warning: can't get
packets: not compiled with polling extensions
I do web search about this error, one answer from
http://pdos.csail.mit.edu/pipermail/click/2011-July/010100.html said I
probably need to add the patch. But the Github said for kernel version 3.2
(which I am using), there is no need for patch any more. And I did not
find a patch for version 3.2 in the repository as well.
So what the problem is? Any suggestions are greatly appreciated. Thanks a lot.
