Do you mean, due to alignment (like uint16_t field cannot always be
placed at an odd-number address)?  If so, the proposed layout took
into account the issue (and that's actually why some of the fields are
placed in counter-intuitive points).  Do you see any specific field
that can cause an alignment problem?
