The private flags field itself is accounted for by\nguehdr_flags_len(), but guehdr_priv_flags_len() currently returns 0 even\nwhen GUE_PFLAG_REMCSUM is set.\n\nThis lets a packet with only the private flags field pass\nvalidate_gue_flags(), after which gue_remcsum() and gue_gro_remcsum()\nread the missing REMCSUM start/offset fields from the following bytes.\n\nAccount for GUE_PLEN_REMCSUM when GUE_PFLAG_REMCSUM is present so that\nmalformed packets are rejected during option validation.",
