--
packet-per.c length determinant dissection is only coded to cope with lengths
up to 127 (i.e. single octet with size flag), so e.g. octet strings > 127 are
not dissected and cause dissection to halt with the unhelpfully wrong message
of "10.9 Unaligned" - the problem is actually occurring on aligned length
determinants too.
