The field "data" is a pointer which points to the actual variable-length option data. So the structure is not packed. There is 4 bytes hole before the pointer in a 64-bit system. The option header is just 4 bytes. When using offsetof() to get the fixed part's size of option header, the wrong value 8 was got. When constructing the encap header, a wrong size and offset was used due to this hole. With this commit, the fixed part's size is calculated explicitly based on all fields.
