3.16.7-ckt3 -stable review patch. If anyone has any objections, please let me know.
------------------

commit 6fb2a756739aa507c1fd5b8126f0bfc2f070dc46 upstream.
Set the inner mac header to point to the GRE payload when doing GRO. This is needed if we proceed to send the packet through GRE GSO which now uses the inner mac header instead of inner network header to determine the length of encapsulation headers.
