But what I then don't understand : Why does the length-field in a
subpacket uese the 1-2-5 octet length conventions ?
Each subpacket consists of a subpacket header and a body. The
header consists of:
- the subpacket length (1, 2, or 5 octets)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- the subpacket type (1 octet)
- the subpacket specific data
I can't see a subpacket type that could use a 5 octet length.
The 2 octet length only goes out to 8128. If you had a longer chunk that
was still less than 64k, since you can't use partial length packets you
would need a 5 octet length packet. I think a chunk of >8128 would be
abusing something, but the 5 octet packet is there for completeness more
than for practical usage.
