6556 * 2) if the tvbuff is "short" (either due to a short
6557 * snapshot length or due to lack of reassembly of
6558 * fragments/segments/whatever), we want to display
6559 * what's available in the field (probably FT_BYTES

6564 * 3) the field is defined to be "what's left in the
6565 * packet"
6566 *
6567 * so we set the length to what remains in the tvbuff so
6568 * that, if we throw an exception while dissecting, it
6569 * has what is probably the right value.
6570 *
6571 * For FT_STRINGZ, it means "the string is null-terminated,
6572 * not null-padded; set the length to the actual length
6573 * of the string", and if the tvbuff if short, we just
6574 * throw an exception.
6575 *
6576 * For ENC_VARINT_PROTOBUF|ENC_VARINT_QUIC|ENC_VARIANT_ZIGZAG|ENC_VARINT_SDNV, it means "find the end of the string",
