What gives you that impression? Where it says The interpretation of these fields is unspecified if either field is less than three bytes (except for the case when dst is missing), it is just allowing for a missing dst field being (obviously) 0 bytes, and hence less than 3 - it is the missing dst field that is allowed to be less than 3 bytes in that case, not the std field. But perhaps that could be clearer. kre
