It failed to ensure that this size was a multiple of 8 (as is required for all but the last fragment), so it could end up generating incorrect fragments. For example, if we received an 8 byte and 12 byte fragment pf would emit a first fragment with 12 bytes of payload and the final fragment would claim to be at offset 8 (not 12). We now assert that the fragment size is a multiple of 8 in ip6_fragment(), so other users won't make the same mistake.
