Subject: linux-next: build failure after merge of the netfilter-next tree

Hi all,

After merging the netfilter-next tree, today's linux-next build (powerpc
allyesconfig) failed like this:

Caused by commit

  bfcf40da7559 ("netfilter: reject: skip csum verification for protocols that don't support it")

I have reverted that commit for today.
