Shreyansh Chouhan 1d011c4803 ip_gre: add validation for csum_start ... Validate csum_start in gre_handle_offloads before we call _gre_xmit so that we do not crash later when the csum_start value is used in the lco_csum function call. This patch deals with ipv4 code. Fixes: c544193214 ("GRE: Refactor GRE tunneling code.")
